Mostly skimming this thread:
Tell that to the people who think they're going to die without Protect though ><
Thankfully, there's an easy solution to that: Go in with Protect in your "first" cross-class slot, cast that, then drop Cleric Stance into the first CCS. You get your Cleric Stance, the rest of the group gets their security blanket, everyone wins!
Sure, there's the whole 30 second lockout thing, but if the group is taking more damage than Eos can keep up with herself in that amount of time, you've got bigger problems. Much, MUCH bigger problems.
