I don't forsee any bosses hitting that hard, unless it's unmitigated. I've heard Hunter pets are able to tank heroic trash fine. With Mail armor and a shield, were basically as close as it gets to being a tank without really being one.

On top of that clearing trash is easy with earthbind totem down a line method. 4-5 Earth Ele's + Bloodlust is more than an encounter is designed for, we pretty much overwhelm the encounter with damage.

For reference if we are able to clear the hardest Heroic dungeons currently, we'll be able to glide through normal instances post expansion They aren't going to make this game insanely difficult and our setups are as coordinated as you can get.
