Someone on a PUG Moonfire a few weeks ago was raving about how wonderful Martial Combat was as a blaster secondary. Curiosity piqued; challenge accepted. Character is currently at level 45.
I rolled a radiation blast/martial combat blaster mostly because I had used neither power set before. That was the extent of the careful plan I made.
Martial combat is ... weird. The sustain power is apparently an aggro aura, which is contrary to the way I am used to building blasters. When running solo missions I have to be careful to leave it off. It does have one virtue in that mobs don't like to be there and get out of melee range. I recedntly took Bonfire to make that more effective.
The signature power seems to be a teleport similar to Shield Charge. I've been using this to port into mobs, drop the PBAoE Rad nuke, and port away, being careful not to use it three times in a row.
The t9 of Martial Combat is apparently a ... single target melee attack. Have no idea what to do with it or whether I need it.
Should I be building this blaster for tanking? An awful lot of these powers are melee or PBAoE, and my favorite blasters have no melee attacks at all.
