To say even a noob couldn't rank up with this exploit is not true, because with more firepower[provided your hitting targets] ranking up and cbill gain, is exponentially faster than using anything smaller(weapons-wise) than a Bushwacker. I use mostly smaller assets on a regular basis, you can destroy folks left and right, but ranking up is slow, and cbills can be hard to come by when having to repair lightly armoured assets often. Slap on a gun or two and your ranking speed flies through the roof. The ppl at the top of the scoreboard are usually very skilled with their favoured asset, and most likely, using assault or Clan heavies to get there.
have fun out there kids...
p.s. don't ruin that fun for the rest of us
