This. I wonder if they take into account the number of highly-skilled players vs the number of mediocre (or even poor) players in their numbers. Player A may get massive numbers on class X, and player B may get crap number on class Y, but class Y may be technically better and the numbers are due to player B being sub-par.
And while I agree this is a good point, several of these currently over performing classes are incredibly easy to play and do not require much skill at all.
I think the main rationale of the OP is to spur any communication between the developers and the players.
Exactly. The issue needs to be discussed and looked harder at beyond kill to death ratios.
