Targeting System

Can you please fix the targeting/aiming system? I try to shoot a witch next to me, it shoots a barrel or crate way across the room... I try to clean out a mob, it shoots at nothing as I circle around it... I don't need to kill walls and barrels, can you at least put a priority on enemies instead of inanimate, non-threatening objects? The new level is REALLY showing this problem, because I shoot for an enemy or Arty the Reskinned, and instead I'm hitting nothing, crates, or even minions... It's beyond frustrating especially when I need just ONE shot left and instead of hitting the target I need to hit, it goes elsewhere, and I get killed...
