Well my druid/4hunter team was shelved. I didnt do too well in heroics but I think others may have done better with better gear. If pets can tank raids then they should be able to tank heroic bosses. Also with the changes coming in the xpac who knows. With the generalization of some key stats it sounds like everyone is going to be stacking more stamina. Give it a go is all I can say. Even though I shelved my team, they were alot of fun.
