Crits are lucky, plain and simple.

First off, this EXCLUDES the Kritzkreig, it's actually awesome.

Critical hits take almost all skill away from the game. Trigger happy idiots should not be rewarded but turning the corner into the enemy team only to come out victorious because of a RANDOM crit. This kind of bad play detracts from the game and removes the line between skill and luck.

Skilled players DO NOT need to crit to take out a team. That's why skilled players are SKILLED players, NOT lucky idiots.
