Tam-tara is such a hard dungeon.

[Alistaire]

You are absolutely right; I've done the same thing and it's hilarious how strong Eos is there as a healer, and how fast the dungeon goes with you as SCH dps.

To avoid idiots like you encountered though, here's what I do:

Set Cleric Stance, Protect, Aero, whatever, whatever. (in that order)

Make sure Eos is out before you queue.

Queue roulette, see what pops.

Capped lvl 15-19 pop Cleric Stance then switch it to protect. This will lock you into cleric stance but you'll still have it up. Kindly explain to the party that you need a sec due to reordering crossclass but they're free to pull first few mobs. If they pull, cast protect when able. Soon as you get protect up, reset the skill to aero between pulls. Enjoy your 15-20 minute dungeon.

lvl 20+ basically same deal except keep protect available.
