Yeah, it's just experimental at the moment. I speced all the druids resto while boosting them to make the boosting go faster. I took them into steamvault at level 61 and was able to heal through the last boss with a double enrage. Lvl 72 +200% attack speed and +150% damage, he goes into turbo mode if you dont kill the little fish tank things. Granted my warrior tank is lvl 80 this just got me thinking.

is it really better than pala + 3 boomkin + 1 tree ? are you planning to try this setup too ?
Well obviously it's better at healing and worse at dps. If you can down a boss in 1 minute with the higher dps group you might as well. If not this might be a viable strat to off spec.

I'm going to try out leaving them resto but out of tree form to see what kind of dps they can contribute while still maintaining a high mana pool and full heals. I will also later try 3 trees + 1 boomkin. One boomkin would more than double the killing speed and 3 trees would still provide massive healing power. I love the ability to heal through anything any boss can throw at you.
