As a sch I'm always going in an out of cleric stance depending on the content. If its something easy like CT, I'm 90% cleric stance, with Selene out. If its t4, I have Eos out, but I cleric stance during the phases with lots of mobs, so I can dot them up, bane, shadowflare, miasma II etc.

Its nice when you're in an FC that's on TS, so you can tell your other healer, hey I'm thinking about doing this.
