Fireburn

Now i'm trying to decide between axe and mace....looking at the powers it seems mace has more aoe but worse proc chances. my initial choice would have been mace....trying to do the math

Hello guys, i have a little question. I'm not looking for best farmer there is, just a character that is efficient enough, mainly to powerlevel my other account. I wanted him to have some kind of powerset that i rarely play and i ended up thinking about battle axe or war mace, with damage procs slotted of course. The plan is to make an active fire farmer, would it be better as a tank or brute?
