Actually, here's a fairly interesting idea for the Turbo Plasma Rifle that I've been mulling over for a while.
Remove the -1 AP bonus on the weapon, add Burstfire capability (similar to the End Boss Plasma Gun?). Make it on-par with high-end Big Guns and the Gatling Laser.
Also, is the range really 35 compared to the standard Plasma Rifle's 24 in this? If it is ever
meant to be added to the game it would be a good idea to reduce that also.

Would like to see it, some variety never hurts, like I'd also like to see any Small Guns apart from the Sniper Rifle be used in PVP.
