Mostly, the AI, and more specificly, the AI of thief NPC's. All they do now is attack as if they were a fighter, leaving them as easy opponents.
None of them use the detect illusions ability to remove your mirror images, blurs and stealth. Only a few with an unremovable invisibility ring will actually backstab and thats just once.
Also, have mages use detect invisibility as well, as this not only gives the cloak of non-detection a practical use, but it also makes the final battle less...easy.
Perhaps even have a few mages/thieves/clerics prepare a few ambushes with glyphs of warding, skull traps and traps?
Also concerning difficulty, Sarevoks haste effect is easily dispelled by a simple arrow of dispelling, making him also, quite a lot easier.
the ai does not adapt to what you do in any way,it just has a set behaviour that it will follow no matter if you're bringing a party of 6 fighters or 6 mages or anything in between
for instance many of the early liches are summoning a pit fiend even if you have already casted protection from evil on everyone and they will not dispel it,thus they end up wasting 5+ spells on their fiend in order to kill him,imo that's not acceptable
assassins only backstab with potions of invisibility and they will backstab anyone in front even if he has stoneskin,thus wasting 100+ damage to remove 1 layer of stoneskin
mind flayers and Mordenkaikens sword or beholders and shield of balduran are other examples of terrible ai,already mentioned
most enemies also react stupidly to summons as they will stand and kill them wave by wave instead of going for the caster that summons them,even if he casted 5 summoning spells mid fight and he keeps going,they'll keep figthing endless waves of reinforcements
also enemies are not opening doors,thus combos like open door/cast cloudkill/close door/profit are destroying them
of course hasted assassins also destroy groups of humanoids for fun as he can just run into a corner and stealth as if he was a shadowdancer with x7 modifier and poison
undead are easy to stack on a protected character and cast a sunray to wipe them
ironically most 'bosses' are better dealt with if swarmed by mellees that use critical strike/whirlwind attack to butcher them in a couple of rounds,they need better ac or hp imo(not an AI issue here)
