I'm guessing that 80% of the complaints about too many misses (just to pick a number at random, hah!), are from people not understanding how Larian likes to use the "verticality" in the game, with the AI sending archers and other ranged enemies to a higher level than the player party. That, or not understanding why enemies like to get behind you.
The Advantage-Disadvantage mechanic for influencing dice rolls is powerful in this game. You have to learn to work with it.
