This is the thread where I will write my suggestions on how to improve ME even more. Don't get me wrong, you have already improved it IMMENSELY. But it can and should be better. For the betterment of (me) all. Right, alphabetically:

BONERATTLERS: The short victory condition is SO CLOSE to being just nothing short of awesome, but it's still not there. Raiding(meh condition, but it's nothing terrible), Ostermark + KK + Kislev are fine conditions here. I would also add Ostland here. But that's just me. Nothing of that's problematic. No. The problem is in the "Raze / Sack 35 Settlements". Because even if we were to add in Osland and even if we were to add in defeating bloodsuckers...THERE AREN'T ENOUGH SETTLEMENTS TO FULFILL THE QUOTA! No way. This condition should be lowered to 25 or, ideally, 20. "Sack / Occupy 20 Settlements" is a perfect condition for Rattlerz. 35 is too much. Long victory condition I'm definitely not a fan of, but it is what it should be. Maybe Nagashizzar could also be moved to short? This faction needs more work imo(in more than one way, but here's what you can do within the scope of your mod).

BORDELEAUX: No criticisms or suggestions here. It is a fantastic faction with a very distinct set of victory objectives. MAYBE Rakarth could be moved over to "Long Victory", but that's literally /whatever . Great job on this one! (the faction itself could be buffed, but that's very easy to do for anyone who as much as tried RPFM - just buff trade and et voila! Instant Colonial Age feel! Or Hlaalu /whatever)

CLAN ANGRUND: The short victory is Belegar's, the long victory is Dwarfen victory. Nothing to it. Except heaps of fun and immersion. Maybe you could keep the "Total severity of grudges less or equal to 5" for every Victory? Because, what if a Grudge bugs out? Just an idea. This goes for all Dwarfen factions.

von CARSTEIN: Again, great job on this one. You can either conquer enemy lands or subjugate them politically. Guess which one I prefer. Yeah. MAYBE Couronne might be removed from the long victory, but that's just a consideration. Seems like you will fight at extreme distances(North, aka Moulder, Front and Western, aka Couronne, Front). Another faction suffers from an extreme case of this, but later, when the time comes.

KARAK KADRIN: The entire campaign is heavily designed around fighting and around Ungrim. I like this. No unification, no nothing silly. Just fight and defeat. Like KK should be. Maybe Gray Mountains should be moved from the short victory. Because I'm not definitely not a fan how the "Conquer" part looks and is the same between short and long victory. Besides that, Barrow Legion is a pain to get to. I'd rather fight and wipe out Norscan tribes, but that's just me. Again, great job on this one.

PRINCE SIGVALD: Maybe different Chaos LLs could have different objectives? meh. I'm also quite annoyed that it's 50 - 80 and not 40 - 80(or 50 - 100, but 100's too much imo) Razed settlements. Besides that, the campaign itself has quite some issues, but none of those are within the scope of your mod. But maybe it should be pointless, to showcase how pointless Chaos is? /shrug

REIKLAND: Here we go. To preempt, Short Victory's beautiful. Unite the Empire. Fair. Reintegrate Sylvania. Fair. The campaign mechanics themselves are quite ♥♥♥♥ and none of their LLs is anything special(next LL is REALLY SOMETHING SPECIAL ; GOLDEN EVEN!). But it has nothing to do with you(maybe you could remove Smashers from the enemy list? /shrug). Now, the Long Victory. Oh, ok. I will bite. Why do you need to build Great Temple of Ulric? First. Second. The amount of fighting on super distant fronts is ANNOYING! Defeat entire Norsca + Moulder? Fine. Defeat Skryre + Sartosa? ...why? Why? That's Gelt's objective, ffs! You're just wasting time and it literally feels like it. I suggest removing Sartosa and Skryre from the long victory. At the very least, I'd like to know why they are here. The entire campaign feels extra painful. Tbh.

SOLLAND: Aka Golden Order aka Geldtastic! Short victory's beyond awesome, congratulations on that. Conquer Nuln, Nuln -> T5, defeat Sartosa + Skryre + some other garbage...defeat your depraved neighbors(bloodsuckers)...GELT'S PLAYSTYLE(makes Teclis look like a fking noob)!!! All's beuatiful. Long victory? Also, quite fair. I'd just drop the Authority system from him, what, unify from Pfeildorf? It's not even Nuln or Middenheim, ffs! But it is probably beyond the scope of your mod. Also, Border Princes and such should really be easier to Diplo with, but that's an easy fix. Defeat Grimgor though? Ok, there's your LONG victory. Overall, a very fine campaign. I'd drop "defeat Grimgor", but I'm lazy and don't listen to that heresy.

TALSYN: My favorite! Maybe short victory should really be short and not include Oak T5 and the final battle? Just an idea. Something like Oak T3 + Laurelorn + 2(or 3 as it is now) Rituals? Something basic like that. Everything else is fine. Now, concerning Long Victory. Gaean Vale. Yes, we need to talk about GV. Ideally, there should be an option to forcefully confederate GV from whomever controls it(just like Wydrioth or like Witchwood etc), but that's outside the scope of the mod. So, what you can do is ... cheat. Instead of "Heal 8(all) Forests", make it "Heal 6-7 Forests". 7 ideally so you can stop worrying and tailoring your ENTIRE STRATEGY over ♥♥♥♥♥♥♥ GV! That and Ok T5 + Final Battle should really also be under Long Victory.

There we have it. All the ME campaigns I have played with your mod. Overall, it's been rather fun, but it could've been better. Mostly due to outside factors, but some of them you can fix.

Thank you for reading and thank you for making this fantastic mod! As I play more, I'll post more. I've already have a critique of Wurrzag ready, if you want it from pure theoretical point, say so. I know Wurr is super fun, but...just say if you want it.
