Pug Raid spots

Got into a raid as a 3rd healer. Keeping the Offtank / Main Tank alive and the other two healers are doing Raid heals. Interesting scenario being a Paladin Healer. The mana demands are heavy. Using a new interface VuhDo to help with the task. Still fine tuning the gear / gems / enchants for optimum output and efficiency. Wish me luck!
