Weird enemy lock in thingy

Hi,
I have 3 characters in the game right now, all of them are to some extend ranged, and I have noticed a really unfun thing that sometimes happens.

From time to time, when I am trying to set up a big DMG combo using ranged skills, the skills sometimes dont actually hit where I am aiming with my mouse, they hit an enemy close to that location. Just a little bit to the right or left.
It is not an issue most of the time, but when it ruins a scenario I was looking forward to(like herding a lot of enemies to one place and killing them all at once) or when it causes the first domino to fall that ends in my death it reduces the enjoyment I get from the game by a lot.

The thing is, I am not actually even sure if it is in the game. It feels like its there, but I didnt see any mention of it in the game settings and it does not seem like many people have that issue or maybe many just dont consider it a big enough issue to complain about it.

Another thing is that maybe it being in the game may be saving me more often that it dooms me, but that is not something I can say for sure without having experienced the game without it.

So to anyone that reads this and has more knowledge about the game.
Is there an actual auto aim component in the game?
If yes, is there a reason it cant be turned off in the settings I am not aware of?

Thanks for the replies in advance.
