I am currently rolling a dual pistols/archery blaster who can take on anything but an AV solo. I grabbed assault, maneuvers, and tactics from the leadership power pool and combined with the holds I get from archery and the secondary damage from change ammo type power I pretty much blow through anything. Just last night on a radio mission team I got attacked by a group hiding in a room no one else on the team saw. They were all over me but with some careful back tracking and slowly taking my shots I got them all and never went below 50% on my health. I also slotted end reductions into everything so my end never goes below 1/4 even blowing through my entire attack chain. This is by far the most fun and best surviving blaster build I have created so far.
