This change might finally enable a team of 5 shamans to clear heroics alone with just the elementals tanking just like in good old BC times. I will check this!
I tested this on PTR and Live servers and the Earth Elemental has approximately twice as much HP on the PTR plus more amor value to tank even more.
I think together with upcoming healing stream/mana spring ttotem changes this is gonna be fun. Not talking about BG ownage lol.
