Regarding Collision Detection/Clipping

Will we be seeing collision detection reimplemented in some fashion? I'm personally not a huge fan of the lack of it for players, but it's not a dealbreaker for me. However, the lack of it on enemies grows rather tiring. Especially with instances such as massive enemy pulls/just big fights in general (Natalan and Cutter's Cry come to mind). It makes targetting rather hectic, mouse or gamepad.

Also, I'm not sure if it's tied together, but the game has some major clipping issues as well with certain pieces

While I can understand the reason for clipping/collision right now, would there be some way to make it less apparent in the future?
