I've sunk a good chunk of change into my Impending Doom PF and finally was able to beat the pinnacle bosses but not with out a struggle (mostly mechanics and dot's). I want to try and make a push for Ubers but clearly right now I dont have the required DPS but I am stuck on how to get there. I've seen steelmage melt Ubers.. is it only possible with god tier gear?

Any help or advice would be appreciated. Thanks!
