Ok I'm finally getting around to doing this... so let me start by saying that I've never really paid much attention to the vanilla items in the game, I just looked for what made numbers go up for what character so I have no real critique on those.
Secondly, I mostly only play 3 classes, Mystic, Warlock, and necromancer; so I'll focus on those three with this... So firstly, props man, I know you gave me a older version of the mod to try out a while ago but sadly I never got around to it until I tried this month, sorry about that.
Secondlt, I'm playing this on the latest version of the game , so I don't know if that is actually effecting the bug I'm about to mention or something else.
Ok Bugs:
I've mostly found only one bug, its that when I use dark ressurection, the negative penalty doesn't end after 3 turns, it seems to continue until they die again or thee match ends...
Now my thoughts on classes:
Necromancer:
This is definitely the class I go back to the most and I love that it was given a resurrection ability and a summon undead ability. even though I'm not a large fan of how they work...
Summon undead ability was kind of a letdown, early-game it saved my A but late game I just stopped using it because around level 25, this thing was just getting raped by anything bigger than groups of 2, attacking with multi hits and dealing massive damage. I was actually expecting non-controllable npc character that would fight with us in matches, but I'm no programmer so I don't know if that would even be possible.
Mystic:
Now the biggest disappointment here was the removal of the resurrected as this was originally seen more as a healer support class in the original game. But I don't dislike the change, to try and shift it into a more control/support class, but it would've been nice to not have the random hit on mind thrust.
Warlock:
Now this, this was just the biggest letdown, and I'm not talking your mod but just the class in general. The original warlock, before they changed it into this whole "hell's fire" class had a crap ton of versatility, mana regen, mana cost reduction, damage boost, single burst damage. I loved it... Honestly, I don't think I can say anything positive about it because I'm still too salty about the change...
Over all the mod does make the classes, with the exception of warlock, more interesting But I wonder do you plan to add more abilities? Because just like with the original game, after a while the abilities do get stale. After a while you just find your favorite ability and just settle into normative pattern.
