My attempt at Totem Shaman:
(sorry for borked screenshots)
Arena 181-185 (twitch highlight)
Didn’t take +1 companion one, because it reduces companions’ leech.
I don’t think you can consistently kill enemies with lightning, so instead of cooldown reset via lightning strikes, I went for Vines. They seem to distract enemies pretty well.
My original plan was to max Static Field and Stormrider, but it seems to be bugged. So I respecced for criticals, though they only add twenty-something percent dps.
Tried the 170 degrees cone and liked it. Also, maxing “On Astral Winds” node shortens your totems reach too much, so I went for added cold damage instead.
