As far as healing goes I would prioritize Sacrifice over Cure. You'll want to get THM up to 50 for MP regen skills as well as Emulate and even Contagion anyway, so getting Sacrifice III is waiting for you up there too.

Cure II is also nice, and easy to get since it's at r20, however generally you only want to use it as a back-up, if even that. With Second Wind II down to 45s cooldown, there's even less reason to keep any Cure spells on bar. Sacrifice is far better for a DoW.
