With DP/MA, I duo with a Arch/TA blaster.
Both around 28-29 right now.
Filled with basic IOs on both, plus a couple extras on both.
I bascically 'tank'. Either start with purples and reds or finish with greens as available.
We set to 5 players.
I teleport in with the MA attack, Dragon's Tail everything, leap out while fire Hail of Bullets, then MA teleport back in so I can kick the remaining mobs, jump out firing whatever is up...
So much fun.
We just roll on through most everything, never ever was able to do this well on Live with blasters until they were Set IOed to the ears.
Do you have a pine build of this? I've been really interested in Martial Combat and been waffling between doing either a blaster or sentinel DP build.
