I'm not sure I'd want more Aetherflow DPS abilities, I'd rather there be more reasons to use Aetherflow on healing rather than almost always on Energy Drain.
Personally speaking, I think they should get rid of Fey Blessing, add a second charge to Indomitability at level 76 to replace Fey Blessing, and then give back Miasma on a different timer from Bio. I'd also love if they attached the old Bane effect onto Deployment Tactics so you could use it in dungeons too! I think I'm fairly easy to please so this would at least give me a reason to play any of the healers this expac!
