unless you just rush in head first like a gorilla then leech and comeback kid are completely unnecessary. i mean really. for 99% of the combat scenarios in the game if you spend the first turn just moving to a better tactical position you can force the enemies to come to you and basically walk into a bottle-neck of death. outside of ridiculous boss battles i almost never take any real damage.
if people can just derp it up and not care about tactics then yeah, leech and comeback kid should probably be nerfed. this is supposed to be turn based tactical combat.
enemies need to look around for sneaked players. there is zero reason a person can backstab someone multiple times in a row and then hit sneak and not even move. who would not turn around and look? just horrendously bad AI programming.
invisibility needs a cooldown where you cannot use it every turn. it breaks many encounters in the game. you can kill the king of frost in hibernia and he wont even fight back if you invis at the end of every turn. he wont summon the elementals and he just stands there. use tornado to sweep away the bad floor and invis at the end of every turn. he will just stand there and let you kill him.
also enemies need to be less scared of environmental effects. you can put midnight oil down to block a path and the enemies wont even cross it 99% of the time. they would rather stand there and let you blow them up than be slowed. its so derpy.
if enemies are to be that concerned over environmental things then give them ranged attacks. throwing knives or something. dont just have them stand there like target dummies.
