Shamans can be so devastated by fear
This is a very interesting tier for each play style. PVP players can skip Totem of Wrath, but for PVE players it is a must-have raid buff. All play styles will benefit from Lava Flows which helps Flame Shock now and will help blade soul gold later. Astral Shift is obviously a PVP-oriented talent and should be maxed out for that play style, but put 2 points into it for PVE anyway because shamans can be so devastated by fear, stun, and silence effects in any situation.
