Fractal 33: Outflanked is my favorite Mistlock Instability (and I think it should be introduced in the open world/WvW/PvP in a lesser form)
HOWEVER there is a problem!
Rare chance you’re on Fractal 33 and roll the Volcanic Fractal, the summoned grubs at 75/50/25 are out of control.
All other fractals are fine, but that one is seriously a problem.. not skill wise on players easily handling that one and other fractals even at higher levels, but deserves a look.
