PC Mouse Aim

This is still an issue after the latest patch.
The game ignores the mouse pointer and shoots in a completely different direction. The more horisontal the mouse is the worse it gets - it can be like 40 degrees upwards from where the mouse pointer is.
I can't understand how is this not bothering anyone in GGG, don't they test the game on a PC with a mouse too, it is not only meant to be played on consoles I hope.
This is the only game that I know of that has broken aim like this (I hope this is not a feature), fixing it should be the highest priority.

Playing a ranger and shooting single arrows is especially silly. What a pitty.

I got tired of pointing my mouse at one place and game shooting in it own direction.
I will be monitoring patches and release notes waiting for this for be solved (removed permanently or at least becoming optional). Until then.
