Drop the Shaman for the last slot and fill it up with a DK?

I never realized that one would opt to not use flame shock when doing a dps test vs the target dummies, since flame shock is one of the highest damage per cast spells for enhancement.

For PvE, yes. For PvP, if your target lives long enough to make that FS do more damage than the ES you could have cast, then something is wrong. FS is one slow DoT while ES can hit pretty hard, especially with the increased crit from Stormstrike.

I'm guessing Ellay saw the loss in DPS on training dummies and put FS back into the rotation. It is a big DPS loss if you're not getting your searing totem damage and buff. That doesn't actually happen in PvP, though, as the searing totem will attack without FS being on the target. In actual PvP, FS has very limited use for enhancement and will likely be a DPS/burst loss compared to ES (that won't be reflected in tests on a dummy).
