actually I was thinking that, as well. but I was thinking 2x resto druids, and 2x shaman for the tank heals, PLUS the AOE heals on rotations, and then spot heals on idiots who need it. Basically, the other two healers would be in charge of raid heals, while you look after the tanks, and use your AOE whenever it's available. Especially in LFR, with the appropriate gear, you control better the outcome of the whole raid..

BUT that being said.. it's a LOT easier to just go boomkins and ele and DPS / faceroll to epics, as well. BUT it takes longer to find a raid, but that's why they invented weights, so i can justify my time away from my computer to work out.

All in all, LFR is fun, and when all my toons have the gear to join, you just have to do it once per team (MAYBE one night a week) and then the rest for PvP - Fun and you are done
