This is a kind of specialized variation of pulling, but it seems to work very well.
I'm a AR/Dev Blaster and have found that TP Foe when used at max range in combination with a Trip Mine or two, produces some very.... explosive results.
Also when soloing against an Orange or Red lvl. Boss, if possible head around a corner drop 5 or 6 Trip Mines at the corner.
Peak around the corner and Snipe the Boss.
Retreat about 30 yds. behind the mines.
Watch Boss set them off when he comes around the corner.
Use another Snipe attack or Full Auto to finish him off.
Flip your roomie the bird after showing him that a Blaster CAN solo against higher lvl foes if they're careful.
