Onslaught difficulty
The current damage numbers and enemy frequency within the "onslaught" difficulty mode is far from challenging, it's just unfair, to resolve the issue a recommended course of action would be to lower the damage levels of the Vel'Koz
enemies, and decrease the frequency of their projectiles, as well as the Kha'Zix
spawn rate. Simply to cause more of this [slayer-pantheon-thumbs] and less of this*[zombie-brand-facepalm]* or just don't, just thought I would bring this to your attention.
