I like a lot of these ideas to some extent. I agree on the HoT or AoE heal being a bad idea if you get down to the core of healing distinction between classes. IE; the arguable order of best group to single-target healing is Drood, Priest, Shammy, Pally. The idea of consecrate having a healing ability is nice, but if Blizz is wanting to keep healers specific on their rolls like they always have been, this is probably not going to be implemented.
I personally would enjoy(though this might seem idiotic to some) a talent at the bottom of the Prot tree called "Inner Demons" or "Skeletons in the Closet" or something to that effect(yes, another lorelol). An ability with no CD and no mana cost. When cast, 4-6 Demons or Skeletons are spawned and attack you with a very fast attack speed. These guys have maybe 1k HP, but only hit for maybe 50 per strike. The point of it being where you're getting low on mana this will get reckoning to proc almost repeatedly. Not the most brilliant of ideas, and not that great for raiding but meh, it's Monday and I have yet to taste coffee this morning.
Either that or another taunt... Again, not needed in a raiding sense, but people pulling aggro can be a constant problem while trying to replace all your greens.
That's all I got..
