My tree is my main character, but lately I've been gearing up my hunter too. While doing these runs, I've sometimes grouped with other resto druids. I can't help but watch them and see how they're doing.
Usually I'm dying to start giving advice.
I don't want to tell people how to play, but it's hard when I see someone struggling to heal a fight I know I could handle with relative ease. When this happens, first I check their gear. If they're in a lot of blues and some greens, I shrug it off and figure they're working on it. I also look at recount. My two main spells are Lifebloom and Rejuv. LB alone counts for 45-55% of my healing in almost all cases. I ran UK with a decently geared tree last week who was struggling to keep up. Her top spell was Regrowth.
I've never tried a healing style other than my own. Rejuv, LB stack, Regrowth (if needed) on the tank as he's running in, then sit back and watch out for part/raid damage while keeping the tank's hots up. I'm starting to work in Nourish as a quick tank pick-me-up. This works very very well for me. Is this an optimal approach or is relying on the bigger direct heals just as valid?
Is it ever appropriate to take someone aside and say "I know what you could be doing to make life easier on yourself," or something to that effect?
