I'm thinking about a druid (healer) + 4x warlock setup for farming
the dailys and questing.

Anyone got some experience in using the felguard as a tank?
I'm not interested in doing heroics or even non-heroic instances...
it's just about tanking an elite mob to complete the quest (like
the 4 elite quests in dragonblight / wintergarde keep) or the arena
quest in Zul'Drak or killing the elite mobs for the daily Qs in icecrown.

I'd like to know if it's possible to heal the felguard or the void
and keep them alive with some hots or are they dead within
the blink of an eye?
