'GOOD MORNING GUARDSMEN!
After only 2 days of play with the DLC I have to decide what to do: ask for a refund or wait for an update.
Since we guards are all though men, not like some ♥♥♥♥♥cat marine in invulnerable armour, I'll go for the second.

BG OF ME
Skip this section to spare time, it's to give an idea of who is talking. I'm a second edition player; tabletop and videogaming warhammer since the '90, most of all Imperial Guard. Well now I'm a rebel of a merchan republic on the border of the Empire, I sold my cadians and I have 3 rebel armies, none created with GW models: a british WW2 army for line infantry, a modern NATO army for a mech force, e GW heavily modified catachan army for some good action. Plus tons of modded orks and some army here and there. I don't play WH40k since the pandemic, don't like new rules, I use simplified ones and play mostly 6mm... BUT... I know what we are talking about here. Like 95% of those who write here, I'm a true guardsman in my hearth. On this forum we can all draw perfectly any lasgun pattern. We here are the real guardsmen.

OVERALL VALUTATION
As we all know here, the DLC is really poor; we stubborn guardsmen buy it anyway, but we are talking about a 15 euro DLC; complete game will be more than 100 euros, money that we earn hard working, exactly like you developers: friends, we all know that money is scarce, time is short, the boss is yelling at you, life is a mess etc etc, but you are basically cheating on us loyal guardsmen :) you sell us guard games just to grab our money, we low IQ guardsmen buy it anyway. You know that we know.
So I can't give the game more than 3/10, starcraft and DOW1 were much better for 30 euros, but let's see if we can have at least something decent, shall we guards?
I helped Matrix/Slitherine with the Close Combat series in the past, and I was a CC5 modder - on small scale, nothing like Nomanda Firefox. But I know a little how it works.

WHAT TO DO
Obviously there are so many bugs, so many imperfections, som many signs of cheap work that I'd really like you to make the DLC from zero. I'd like to see so many improvements that they will exist only in my fantasy. So let's keep this as short as possible and focus on what can be actually done. I'll present the main corrections you should apply to some units without changing too much the game mechanics; this could go on forewer, so I'll let other suggestions to other guardsmen.

(A NOTE ON LASER)
Ok men, the developers made it clear: from now on lasers will be non-lasers. Deal with it. As someone wrote here 'We are all wrong, except that guy from GW that decides'. The game is GW propriety, what can we do, call the police? We can only no-to-buy, but we know that we buy anyway. GW is not a democracy. In our long WH experience we saw many horrors: necrons going from terrifying xenology creatures to egyptian puppets with feelings, Dark Angels accepting some stupid clone-marine into their more secret inner circle, Cadians being the main force even if their planet is destroyed, and so on. Get used to it brothers.
Let's say so:
'SOLDIERS! From now on forget your standard lasgun with 30 years of history and all. From now on is WW2 again: ww2 US helmets, ww2 US heavy tanks, ww2 field guns and THIS! WW2 M1 garand lasgun! ACCEPT IT, THATS AN ORDER!'. So we have to assume that a lasgun use laser to heat some gas chamber, then emits an high-energy bolt. That is stupid because a battely is not enough, you need more complex clips with gas, you cannot recharge it on the field, you cannot shot in void, you have to remove those lens from the barrel, and for the second rule of thermodynamics adding a passage to the process decrease the overall energy, but that's it, brothers. Let's accept this, we are the losers here, but we are used to it, we're not ♥♥♥♥♥cat always-winning marines. Move on, soldiers.

HUMAN PROFILE
The profile system is really broken in this game; for example, a Tau infantry should be same as guardsmen with +1 armour; well, it is double health and double armour! This makes a whole mess on all the game. At least make humans HP 40, Armour 3. At least. Fix it as you can in this cheap way, but do something! That's horrendous.

INFANTRY SQUAD
The lasgun is not the man infantry weapon, the main weapon is specialization. On a 10 men squad you had sargent with boltgun, radio operator to boost tactics, special weapon man, 2 heavy weapon men for a total of 5 specialists out of 10, the other 5 probably carry ammo. This need to be reflected in game. You'll never add animations of guardsmen putting away the rifle and taking a grenade launcher, but at least allow the 'grenade' ability to be used without action points (AP 0) in ADDITION to lasrifles, and cooldown 1. Those are GRENADIERES!
For the assault version, make the bayonet to create area of control and to be used also when attacked; in addition add a 'Demo charge' ability (AP 0, cooldown 3, range 1) in addition to lasrifles.
For the normal squad add 'Take Cover!' ability: consumes 4 movement, increase the cover of the squad by 1 point; IF YOU HAVE TIME FOR IT, it would be delicious to make guardsmen go prone.
For the assault squad add 'Pike Wall' ability: consumes 4 movement, the squad greatly decrease the enemy melee accuracy.
Increase las shots, right now they could not kill a naked human running at them all the rifle range. It's pathetic.

HEAVY WEAPONS
Add reloading crew animations for all 3; that's a must, my friends.
If the autocanno shots only 2 times, slow it down BLAM... BLAM... anb add recoil and smoke, but please make its ability to shoot many times working. On my pc it shots always 2 times.
Lascannons: add seriuos recoil and a serious muzzle flash, il looks like a lego stop motion movie right now; it should be like a real ww2 anti-tank cannon ZZZZOOOOOTTTT! And, really, make the bolt faster, it looks a poor ballista shot, scares no one; make it 5 times faster, like ZZZAPP! To look more deadly and 'realistic'. Same for the multilaser.

TANKS
Add standard leman russ as basic, only then add special lemans.
The leman is one of the few WH tanks with tank leader; add an ability 'commander periscope' (AP0, cooldown 3) that increase the detection radius.
Please, add more smoke and blast, both to the gun and to the target. Those look like poor 50mm panzer III guns. This scares no one. We need a gun that BOOOOM and a reciving with tons of smoke and debries. Go watch some Ukraine footage, they have 120mm guns, and lemans have from 120 to 360 depending on who is writing the BG.

BASILISK
Bugs are everywhere in this DLC, but the basilisk... OH GOOOOOD! It's madness. I played 2 days: the tracks now roll on the wrong way XD and in a game it used to shoot 3 tiles further; to correct it i moved the basilisk 3 tiles back and... IT WORKED! Oh Jesus.
Anyway, the vehicle without reloading crew... make it closed, or better remove it and make it shot from aoutside the battlefield!
And the projectile: that is a playmobile cannonball, please. If you can't fix it at least make it invisible.

It could go on forever, but I let more practical suggestions to other guardsmen. Thanks brothers.

Dear developer listen: we know that you have to earn the bloody money, as all we must. But remember your honour, your dignity; respect our dreams, respect the child that is inside every guardsmen's hearth. We are already creating a psy-choir to send nightmares to those GW businessman that never read a good Ballard sci-fi novel in their life, and only think about the next move to steal money to our poor souls. Don't be like them, don't listen too much to them. Listen to us. We are giving money and time. We are the army that keeps all this going. We are the people.

I'm wide open to suggestions.

Thank you very much friends, for the time and all. And let's hope for the best :-)
