oh lol, haha I meant Inner Fire of course. My apologees
Dispersion is in my opinion a very viable 51-point talent. I use it all the time in PvE. It's a "Get-out-of-jail" free card that you see Rogues have too many of as it is. Specially on KJ I use it if the dragon is too far away, or if it gets hectic. It's a 5k hit, but alot better than a 45k one
