does my fire/mm blaster love I16?

a basic issue in CoX is teaming vs soloing builds/sets.

My DM/WP loves soloing because he has good single target effects.

My fire/mm blaster hates soloing and wasting his aoes on 2 or 3 man spawns. But upping the difficulty and getting higher level and more foes doesn't work well.

So now I wonder if I can set my blaster to face foes as if I were on a 3-4 person team, but at -1 or -2 levels - and get missions filled with minions and lt's that I can devastate with aoe?

that might make soloing with him not feel painful - as well as being fun
