The problem is that monster hitboxes are wildly inconsistent, so 1~2y would be a huuuuuge QoL improvement. It’s often close to impossible to see that you’re not standing in range of the clump of mobs while the other mob you were kicking before was in range just fine.
If they insist on keeping the majority of difficulty in M+ on interrupting, they can at least make it less obnoxious for melee.
