3 our defence are really bad healing tide totem people kill the totem all the time earthen wall totem the vision really bad and pvp people keep running from it, totemic projection is aways bug, astral shift i die in my wall 2 melee
4 a lot dead talents ancestral awakening 2 point 1.5 million heal 1% that really low for 2 points.
5 as shaman you need 9 clovo to make a ok heal for 150k that a lot
