I've been healing randoms leveling 80-85 primarily by using 3x lifebloom then spamming healing touch on the tank and using rejuv with the occasional regrowth or healing touch on the group. This has worked out fairly well except on some longer more damage intensive boss fights where I oom. I also oom fairly often on trash, but I believe this is a result of my gear not my healing style.
However, I've heard from several other resto druids that healing touch is bad and that I should either use just hots or use nourish instead of healing touch. This is very confusing to me since unbuffed my healing touch hits for 15k avg while nourish hits for 5k avg. This to me says they have the same mana efficiency and the same cast time. Obviously there's a greater chance for overheals with healing touch, but I've found many circumstances where the group has taken enough damage that nourish simply will not keep everyone alive due to the long cast time. I'm aware that nourish hits for 20% more when a hot is active, but again, in most cases when direct heals are necessary on the group nourish just takes too much time and that 20% doesn't increase the mana efficiency terribly much. Plus healing touch also seems to heal for more (not 20% more, but more nonetheless) when a hot is active?
I have, on a few occasions, tried a hot only or nourish instead of healing touch strategy and find that I'm ooming just as much. I do use Innervate 60% and Potions of Concentration whenever I have the time to spare (still using runics for when I don't, though). So I'm looking for a little clarification as to why I'm ooming (again, I assume it's my stats) and what I can do to avoid it. I think the answer is that reforging may help, but I have not tried it yet.
My stats (unbuffed) are: 54k mana, 2712 int, 1783 spirit, 4306 sp, 972 haste, 432 mastery rating (which I guess I should reforge to int?)
