Heya! First off, this mod is absolutely awesome and beautiful. It truly scratches that Steppe-Horde itch I've been nursing since playing Sarmatians in Rome I Barbarian Invasion and Khand in ME2TW Divide and Conquer. I love it. I just played through 100 turns with Ur-Khan with 80 mods enabled including Mixu's Lords, IEE and LCCP and didn't have any weird crashes, glitches or whatever, and I'm running this on a sub-optimal 4gb VRAM laptop.
There are just a few suggestions (which can be ignored of course) that I would like to make to you that could make it even better perhaps:
-More things to do with Khan's hoard and Plunder. There is frankly not enough to do with both, especially Plunder. Would be awesome if Tribal Gathering buildings were only buildable with Plunder and Khan's Hoard as that would incentivize you more to go and, well, raze and plunder.
There could also be a few more upgrades in the Tech Tree purchasable with Khan's Hoard like factionwide stat boosts, hero/ROR unit recruitment slots, and/or wargear.
-Better Adaptive Warlord units for the Land of Chill. Honestly, in 100 turns I didn't feel the slightest inclination to recruit one of these units, neither in the early or late game. Harpies? The Vultures are better imo. Daemonettes? Thematic but not really needed. The only units that stuck out to me as reasonably interesting were the Hydra and Scourge-runner... And maybe the Reaper but I was going for highly mobile cavalry armies so the Bolt-Thrower didn't fit in with with my subjective play-style. And are any of them worth the prize in Khan's Hoard? Not really, no... Except for the Hydra. They feel like weak early-game units, easily ignored in favor of the Standard and ROR Hung units. And yet it is a great system and there is so much possibility! Heavy Lancers on Cold Ones, Horsemasters/Khevtuul with Repeater Crossbows, enslaved Daginakh Sorceresses, tortured Bloodwrack Medusae. Hung Cold one Chariots, Hung Spearmen/ Halberdiers decked out in Dread Spear/Black Guard armor, Ambushers/Tchar Shamans on Pegasi and perhaps more. What I'm suggesting is making the AW units powerful end-game units that are worth the investment.
-The possibility of trading. It says so in all the quotes and books: NOBODY trusts the Hung, but many will still trade with them.
-The possibility of recruiting Daemons of all 4 Chaos Gods, lesser/beasts/greater/cav, at Tribal Gatherings, perhaps unlocked through the 4 rites? It would add a bit more variety and RP possibilities and it corresponds to the lore (if I haven't completely misinterpreted the C.L. Werner books of course).
-The possibility of recruiting mercenaries, of the Norscan/Chaos/Chorf/Ogre persuasions, at Tribal Gatherings. See above for my reasons.
-DREADED WO FACTION WITH PIKES, REPEATER CROSSBOWS AND CHAOS CATHAY UNITS PLEEEEEEEEEEASSSSEEEE!!!! THEY WERE ONE OF THE COOLEST PARTS IN THE ARCHAON NOVELS!!!!!!
I don't want to sound over-bearing here. Your mod will remain absolutely and undeniably awesome to my eyes even if you ignore these suggestions. You must have put an enormous amount of time, work and passion into this and it shows. I myself am starting to mod WH3TW (making patches mostly for personal use though I plan to upload them at some point) so I know that creating a unique faction as detailed as this one must have been bloody hard. I just hope that I stoked your fires a bit with this. Thank you very much.
