Firstly, I don't have a priest, so I don't know very well about these abilities. But I'm interested in playing one, so here's some theory crafting.
All of these spells are fast cast spells (1.5sec to instant). Each of them has roughly 1000 base heal for 10% of base mana. I assume they scale very similarly.
My question then, is why don't Holy priests run right along side their PvP buddies so they are always in range of AoE healing. The opposing team would be likely to try to attack a priest that is so close by--but doing so would leave your partner free to take them down (or if you have a tank partner, to protect you). If the damage is split, all the better--less of your AoE heals goes to waste.
I find this tactic to be interesting because if you stack crit chance, you're most likely to crit at least once on you, your partner, or your target using spells like Holy Nova. This gives you an extremely high chance for Surge of Light proc for free smite, or a free Flash Heal. This should give you quite a lot more survivability.
By the way, can Mind Flay crit? And if it can, does it proc Surge of Light as well?
