Get Close Enough and use the Fibber, Twister, and Hyperion plasma casters. --- http://i.imgur.com/qfsbZAm.png -- GT: Gears of Wario Now Playing: Borderlands 2/Battleblock Theater/Far Cry 3: Blood Dragon
Close range guns will be your best bet. I run an OC/LBT build and I use SMG's and shotguns... along with a launcher to quickly get me up in FFYL (you lose anarchy while in it). The others that posted were right though... the twister and other fixed pattern guns are good things to try out... Also the stalker or (whatever the new version of the stalker is called) mixed with close enough are good guns to try... --- GT: Steve0314
Striker, Conference Call, are good for stack building. Seeker is good for taking advantage of stacks without the need for accuracy.
DP Unkempt Harold is a must, at close range this pistol will obliterate everything in you're path and with only four pulls of the trigger you can empty its clip pretty quickly so its also decent for stack building.
