personally i would say no to totem of wrath is not pvp suited, i dont think there is a single serious pvp elemental shaman takeing the totem over a the 'nuke button' (em+ns combo)

ToW is great for pve, the increased hit and crit is godly as it stacks, and even in pvp it is still very nice to have the extra crit, but i would rather have the nuke and just keep the searing totem down.

I think it comes down to if your spell crit is high you wont really depend on the totem too much so its better to take Natures Swiftness over the ToW

Ever since i saw tow talent i never considered it a good 41 point talent compaired to what other classes got, the only good thing about it is that it stacks. Come Wrath ill be getting it as the new 51 talent sounds too good to pass on.

hope this helps you
