Well since no one's replied yet I'll post my expensive Rad/Mental build to give you some ideas on sets and power selection. Mind you /Mental is not nearly as damaging as /Fire for AoE but Drain Psyche is very nice if you're facing a lot of melee enemies for an extended period of time.

Hey I'm pretty much looking for a build that puts out a devastating amount of AoE Dmg, I have pretty much come down to Rad/Fire as a set choice and was wondering if anyone has a build handy, i'm open to suggestions of other sets if you think there is another pair that would out perform this...
Few points to note:
Influence is no object.
Main enemies will be mainly S/L damage dealers but I would like to use in TF's too.
I play fast!, endurance is a huge issue usually
thanks 4 your help
