I very much dislike the gauntlet trials due to mouse control

The mouse controls are absolutely running the gauntlet trials for me. They are beyond frustrating when I take damage from a trap when I clicked my char to move via mouse control and it goes PAST than where I clicked.

The only trials I have really struggled with are these ridiculous gauntlet trials with very small "openings" for the flame traps on the level 62+ trials using mouse control. I would recommend either fixing mouse control so it doesn't move past where I click OR make the gaps a bit wider. At this point they are no longer fun and more frustrating which is the opposite of what a game should be.

Due to this I very much dislike the trap rooms any more and avoid them at all cost.

PoE2 is optimized for WASD and Controller movement.
Try it!

You basically described every problem with movement in PoE1 and exactly why WASD movement is a godsend in PoE2.
