We are the MT of a dedicated 10-man guild, but we're serious about our raiding. We have since cleared many Ulduar hard modes and are just Firefighter away from Algalon. We used to run with an unrelenting assaults (UA) build besides a 15/5/51 in the T7 content. In Ulduar we switched our 15/5/51 to a more defensive 5/10/56 build with 5/5 imp demo shout and defensive glyphs to survive the hard hitting bosses. The shorter CDs on shield wall and last stand were especially helpful for progress. We got the DFO information from other website.
