Repost of my post on the WOTLK forums:
This is not my idea but it is the smartest idea I have read on the forums so far. I am not in Beta but i dont like the way it is going at the moment. I have healed Sunwell on a paladin.
Many paladins say that we lack some "kind of" AoE heal and i agree: holy shock on a 6s cooldown and Beacon of Light is not sufficient and might be a wrong approach.
Well,
we dont need HoTs, we dont need a straight down AoE heal. It would require nerfing on our single target healing to even up again with the other healing classes.
But,
we do need a spell like PoM. A spell that is reactive to damage and does have some AoE ability.
Option 1:
You could combine this with Sacred Shield ( jumping to damaged players, preventing the next damage), giving us the ability to land a crit on them. I suppose that a less good version of Sacred Shield should jump over, like only 25% crit increase but with the full strenght damage absorption (6 sec duration). Then we can heal that target up, while having beacon of light and the original Sacred Shield on our main target. (something like 3 jump charges would be nice)
Option 2:
We get a spell like PoM but you then need to tune down Beacon of Light to about 70% of our healing done but including the heals PoM do. We then heal less double targets but we gain AoE survivability and improved single target healing on massive damage spikes.
