No.. no.. no. Duals were never part of the original GunZ and they can't really be turned into something better than they are right now as that would make them OP and stronger than shotguns, V7 all over again. Dual Rifles also aren't really meant for serious everyday PVP combat. Single rifles are fine, you should try those.
This, let's not repeat the same mistake.
I may or may not have abused those dual sprays in PVP.
Also: I have been informed about an issue on the dev server, so I'll postpone this update for 1 day to look into it and fix it. NAT / AE will also be looked into while at it.
