Necro post?
For now i have dropped using GOC/GOB in groups (Heroic) and I just toss up an extra HP buff on whoever gets hate the most. As Mafoe said before, with the stuns, I rarely have to direct/reactive heal.
Stun, Involuntary gift, Mark, Def debuff, shield bash, stifle, amending: By the time that rotation is done, the mob is down

Works great. On the longer fights I will kick out some DPS and maybe toss in reverence before the fight, but usually amending goes off enough to keep the big boys in the green.
Can't wait until I have more AA's and snag the TSO options. Should be a lot more fun solo and in groups.
