Not to overuse an appeal to authority argument, but so far the only weapons that seem to be in agreement in OPness is the Raider SMG and possibly Ranger thumper. The hitscan weapons don't even register in the list. Ranger assault rifle is a less effective weapon than the Soldier's pistol.
Also, three more keys.

Finally, don't be quick to call out aimbots. Most the folks I play with regularly get called out for it, and it gets really annoying. I'm level 17 or 18 right now, not sure what that means in playtime, but I've personally only saw a single persion that might be an aimbot user, but it was even questionable.
