Impale causes massive lag on PCs (probably servers also).

Why isn't this at least a known issue? Few people know or are complaining because they are mostly playing elemental or crit/slam builds. But it has become impossible to pick impale nodes on the skill tree knowing you will be playing on 15-25 fps after 30s of mapping.
The lag disappears on instance reset so it's not exacly a mystery what's causing it, though it won't be seem as a bug...
I won't keep my hopes up that it will be fixed this league, but at least GGG could acknowledge it so people won't think it's their computers fault.

Agree it's a dog sheet gameplay. That mechanic is so powerfull that even your CPU give up.
-More monsters = even 60ms on CPU <GPU max 16><i HO 3-4 > , w/o impale i have max 20ms .
AFter using portal and qucik come back to map all lag disappear.
It's smth with left bodies and calculating impale on them <maybe>.
I also play Cyclone of tumult. APS make it even worse.

The only way to mitigate this is destroying the corpses; use shattering with some cold, or explode in some equip like oriath end
