TuggerKanecoPlatinumAmbassador has potential to unlimited headshot .. Diamond back gets one essentially after a kill, why is bannable?because one rewards skill and the other doesn't?
I'd sooner say one rewards aim and the other rewards a backstab, so they both reward skill if we're talking about a 6v6 environment where backstabs aren't mindlessly easy to pull off.
As I said I think getting a crit is a huge reward for a class that is literally designed around the 1-hit kill mechanic.
Maybe get a mini crit for each backstab would be more balanced? Or remove the 15% damage reduction entirely, put a slower firing speed like the amby (or smaller clip size) and reward kills and saps with minicrits instead of crits?
