Now, correct me if I'm wrong on this assumption, but doesn't the fact that a fourth to a third (or more) of anyone's kills come from a single weapon (rocket launcher) point to an obvious imbalance between the weapons? And I'm talking decent players; one's who you would expect to use all the weapons skillfully.
In JD's case, 31.71% of all his kills are via rockets. Another 15.83% come from flak. That's nearly 50% of all kills from a mere two weapons out of nine. Isn't this exactly what everyone complained about in UT2004? Only instead of rockets and flak it was sniper and shock.
Same problem, different day. D:
