The Dev's outright stated that the flat % Buffs will never go away. While I'm personally not a Fan of AI Crutches such as this, I get it to a degree in this case. Like Nenjin said, programming a decent AI for something like this is hard. Heck, bigger Series like Total War with a lot of dough behind them still have relatively "dumb" AI.
I've played for another 4-6 hours now. And I gotta say, I'm pretty happy with the changes. The game is still hard, mind you. Well, depending on your Luck with Deployment of course. But Normal Missions at least, now feel like you're going up against something that is roughly your strength. Or rather, the AI stupidity now more or less matches the 10 percent buff they get. I also played a couple Hard missions, and they are doable to the point that I flat out recommend going for them instead of normals, because of the better loot and extra XP. Havent tried Brutal or Deadly yet, but I'm reasonably sure they are adequatly named. Had some tough fight on hard, so I'm not keen on testing out Deadly.
There's one gripe I have tough. And that's the fact that progression still feels unsatisfying. And since we wont see those crutches for the AI go away, this might not change, even in the far future. Basically, when a game has Character progression like this, a big part of my enjoyment comes from seeing my guys grow. To compare it to Darkest Dungeon, I love the feeling when your heavily upgraded highwayman deploys deadly crits, or your high level Crusader tanks hits like crazy, thanks to Trinkets, gear and abilities.
In Mordheim, I dont get that a whole lot. Like we established, most Skills are very low impact. I took Acid Breath on my Sorcerer, because I felt like it would be the first big Upgrade on the guy. But it deals 12-19 Damage a piece, and the Hit Chance is low enough that you will probably miss 3 out of 5 guys with it. The same goes with everything else. It's allways this little percent increases. 5 to Dodge, 4 to crit etc. And the impact is so low, that you barely notice it ingame. Exception maybe being Range increases, you definetly notice those right away.
This is a purely personal gripe, might just be me, but I would've much preffered if they increased the numbers a little. More hp, damage etc. And in turn gave the Skills, Spells etc. some more Oomph. Most of them are way too situational, others flat out do to little for their price and time investment. I think that one Goblin Comic describes it perfectly:
http://www.goblinscomic.org/12152005/I remember that one battle after I just reached Warband Level 3. Suddenly a lot of enemies had skills. And I remember that they used them in every engagement. But it either missed, didnt do anything of note, or was barely noticeable. Again, this is just me being petty, probably. And they'll work on it in the future, I'm sure. But it's one of the things I noticed more strongly, the longer I played.
