Honestly, after 400 hours of regular missions & chaos wastes, the weaves have been a massive treat to finally try out for the first time tonight at the time of this review. Me and my friend are really enjoying the new variety of how the maps have been changed / opened up, as well as the unique (or different, at least) system for upgrading weapons with the Essence (which can be earned playing normal missions, good thing to allow).
The Weaves are freaking awesome, cant believe I've just now tried them. The increased amounts of enemies & increased variance of them is a HUGE aspect I've always longed for within the Warhammer world. Overall, the Weaves have been incredibly fun.

The biggest thing I am psyched up about with the Weaves though... The amount of enemies. There isn't just 1-2 assassins at a time, or 1-2 ratling gunners, or any special or any regular rat... there is a TON.
It makes it feel as if there are genuinely whole regiments of clanrats, Stormvermin units, packmaster throngs, etc; being part of an entire army / invasion force / vermintide! (hey, thats the name o' the game!).
This aspect is, while extremely difficult at times, important for me because it makes it feel like how I've imagined a Warhammer world to be more akin to in such a scenario/story. These Weaves make me feel more like I am in a Gotrek & Felix novel, battling an entire platoon of Stormvermin backed by a regiment of Ratling gunners, while a entire troupe of Eshin assassins prey upon us. Not just 1-2 at a time, or smaller cells planted around... (which btw, IS FINE. Not knocking that; it is perfect for the main missions, and still makes sense). This feeling though, of the overwhelming odds, full platoons of all units; feels to me, a step closer to Gotrek & Felix, which I grew up reading as child (and many other Warhammer novels), and is so, so, awesome to have found out.
And ofc, this variance/randomness of enemy amounts allows for different fights/odds/challenges compared to how the other modes operate.

So, with this said, the Weaves feel like a really big breath of fresh air & a very fun time. This mode is NOT, however, perfect! No- it is SUCH a shame that upon release, & to this day, WoM is racked with negativity & seen very poorly. One of those moments wherein actual, constructive critique, suggestions, wishes, etc. from the playerbase would've been better over the usual type of whines, rants, comments, etc. from the internet...

It'd be cool if there were extra modifiers and character talents/traits in the Weave mode, as this would add a more unique spin when playing them compared to running regular missions or Chaos Wastes. And with the overwhelming/increasingly difficult odds faced in the Weave missions, it'd be cool to have some, perhaps specially modified, type of passive talents for our characters. Not to make us overpowered or superheroes even, (though we are Heroes of some degree just like Gotrek, Felix, Max Schreiber, Ulrika, in the books etc), but some simple passive traits, perhaps like, racial attributes... (Elf gets attack & movement speed, as is natural for an elf; Dwarf gets damage resistances and strength buff, as is natural for a dwarf, etc.. or something along these lines).

Here's a BIG one: Simply more variety of mission objectives would be so nice (there is a fair amount, but, this is a spot where, just adding more variance would provide such increased depth/fun/repeatability for us players).

It's a true shame so many responded negatively to the Weave portion of this DLC. It seems really awesome to have able to play after running through the main game missions more times than can be counted, aha. Definitely deserves more of an open minded outlook on it...
A revisit is needed from most of the community, imo.
Look at what it does provide, add, & make one feel! Constructive feedback at the time of release could've possibly helped make the Weaves into a truly fleshed out and damned EPIC experience, & we could've had the Main Missions, Chaos Wastes, and Weaves as full on different modes/areas to replay over and over... Endless fun!

FatShark, you could improve upon this DLC by:
1. tweaking the ability for some traits/special perks for Weaves only
2. some more mission objectives relating to essence & weave based things
3. map/enemy/character modifiers, akin to how the Chaos Wastes DLC works
These 3 alone would surely improve the fun/repeatability of running Weaves for a good deal of time... (these traits/objectives should ofc be specially made for Weave/Essence related tho, not just copy & paste as it wouldn't fit the theme & add to a distinct feeling Weaves actually provide).

Quick-Notes-Thoughts:
1. Add some new objectives based around the Essence stuff. (just increase the variety, that adds tons of replay-ability itself).
2. Talents / Race attributes (smaller amount of talents available, new ones, Elf is fast, Dwarf is strong and resistant, etc)
3. Modifiers of players, enemies, & levels (akin to the Chaos Wastes, but special for WoM)
4. The openness of the maps is really unique. Instead of going through from point A to B like in main missions, in the weave missions its more of "go wherever you want in this space", and thus the whole map is more open. This is a very cool element on its own that could *definitely* be expanded upon, even beyond just WoM/Weaves... (imagine creating a mode with a more open based map, where you survive/hunt/complete some objectives).
5. Spice it up a bit more, Flesh it out a bit more, Variety is the Spice & is great for players & repeatability in general. Keep the aspects that make it different and unique from the other modes... (again, the absolutely bonkers amount of enemies is a key component!)
6. I know I repeated things a bit throughout this, but I was & remain blown away with how awesome the Weaves are, & the POTENTIAL they have to become a full fledged, amazing & endless fun mode...

That's all for now. Very glad I tried the Weaves out for the first time recently, as they have sparked an unlit flame for the game within me again! I feel that this is/should/could be such a huge step/spark for longevity of the game that could really take hold still.
The negative rating is a bit unfair, as besides the Weaves, all the other stuff is fairly great (weapons, difficulty, beastmen).
