Reading through the thread I guess best I comment on my thoughts on the 3 ideas I put in OP.

I don't want them to do that stuff but those are their options, their intent with the healer changes is they want us to heal more, a fine enough intent but their execution to try and get us to do that is WRONG.

But they can't see that the stuff they have targeted as the reason for our more dps focus is WRONG, they blame the dps abilities but it is the healing abilities that let us dps, it is the fights that allow us to plan things out so we do as little healing as possible.

They do not realise why healers do as much dps as they do and it is this mentality that needs to change, they need to understand why we do as much dps as we do and until they do they will continue to make the same design mistakes. If they don't realise soon I can very much see for 6.0, Sch lose Energy Drain AGAIN to be given it back later AGAIN, even simpler cards, and 1 button nuke, 1 aoe nuke as the dps rotation no DoTs because they still believe it is the Dps skills at fault, I could see even more ogcd heals added making you never cast a gcd heal.

The developers need to wake up and see, they are wrong with their design mentality for healers, and this is a fool's hope that when they get that realisation that they'll look at all 3 healers and go "What have we done".

But those suggestions in OP are ways for them to keep their current intent just as I stated in OP the playerbase wouldn't be able to handle them so if the solution to their issue cannot be done perhaps it is time to rethink their approach that is causing the supposed issue.
