I think, dice rolls work against the party and in favor of enemies. I mean the game lets you take several rounds to kill off a goblin with 2 HP left, because your characters miss every fucking attack at 60-70% chance.
Also enemies often get various benefits at combat start from outnumbering the party while having almost unreachable high ground, setting half the group on fire with the first attack and so on.
I'm avoiding combat (which costs me xp) and even reload if persuasion checks fail and combat is at hand.

Example: Battle in Destroyed sanctuary:
The goblin outnumber you by far.
The casters and archers have high ground advantage. While you have to even get into the lowground area in order to get into further combat.
They seem to have a lot of casting abilities, counting alone the 3 times one goblin made Lazael fall asleep.
Two archers climb up the long ladder and have easy attacks on you, while you need a long time until you get up to them.
The goblin priestess throws the large statues at you, again you have the problem of being on low ground here.
