First of all:
For a 2-hander, the last points have to be spent on Falcon.
Reason: Shamans have Heart of the wild and Wendigo totem, solving all of your survivability needs (the 2-handed lightning Warder version tanks Avatar of Mogdrogen easily, I tried it). What they need is offensive ability, because of the huge crit bonus from Stromcaller’s pact.
Primal strike seems better than Savagery. They do around the same damage, but…
- Savagery only works for Warder (2-handed) or Trickster (DW), with Warder still being better off going Primal strike. The reason is that you need the attack procs for aoe.
- Because of #1, Primal strike needs much less points invested
- PS triggers Falcon swoop twice as often.
