I also add one (since i don't think it worth making a dedicated topic for it) : status effects are overwhelming.
Just for movement penalty there's 5 (if i'm not missing any) : hobbled, stucked, stunted, paralyzed, and petrified.
And there's almost as many spells to protect from it, but not for all of them (i think there's one for stucked & stunted, and another for parlayzed & petrified) ; same thing for mental penalty.
I have played this game like 60h (and obviously i like it at lot) but i still can't remember where is priest/druid/mage spell for each particular status ; to counter a negative status i keep scanning all my characters for spells i don't even have ! I can't remember if a particular monster type stucked me the last time i encountered it or if it paralyzed me (except if it was 30sec ago, i'm not that dumb ^^), and finally, i can't even tell without checking if been stuck is worst than being paralyzed !
In Baldur's Gate, I just had to use "freedom of movement" and it was all good no matter if it was just a spider web or anything else (except petrification, but the difference was very clear since it was a permanent state), there wasn't "lesser freedom of movement" or "freedom of movement only vs spiderweb" spell and i don't think this would have added tactical depth.
