Wouldn't we need a enemy collision-circle resizing function for this? They're already packed as tightly as possible in most cases and we still can't AoE all without the tank ensuring a small mob is in the center of the fan of mobs.

Of course, I'd be all for said feature, perhaps even atop just shrinking down the oversized circles generally. (We see this most often on quadrupeds where the circle seems to be drawn according to their lengths, not widths, so mobs can't much clip through each other. But, since they're most often shoulder-to-shoulder (i.e. at width) in combat, this tends to just make them seem weirdly spread out.)
