Were you using grounding totems, if so, were they helping at all?

Nope. None of the totems help, and your fire ele/searing will turn against you. See below.

I tried everything. De-equiping my weapons. Laying stoneclaw totems (that helped, fyi. It was hilarious). Using earth elementals after MC phases to pick up aggro. Potting. Judgement of wisdom. Rank1 Holy Shield/Righteousness when oom. Grounding totem (FYI, doesn't work -- totems turn red during MC). Blessing of Wis. Salv. Kings. High burst ASAP. High regen/longevity. My shaman would get pwned every single time.

That 'Time for Fun' boss is a killer. The best way I've found for shammies to get past him relatively easily is to blow all your cooldowns except for Earth Elementals (use your fire elementals on the earlier groups in that room).

Speaking of fire ele, not once in my bajillion tries did they ever pop an elemental. They popped heroism, but I didn't see them lay a totem once. This may be a mechanic of the MC - since the MC "knows" that the totems will turn red (see above) and turn against you, there is no reason for the MC artificial intelligence to drop ANY totem as they provide zero buffs.
