I tried for a good 30 minutes on the target dummies to come up with a Boomkin castsequence and could not. The eclipse stuff is very annoying. You would need two macros depending on if its in moon or sun, you would have to constantly check your boomkins to see which macro you need to use depending on if they're in moon or sun eclipse and then use the appropriate macro, then switch once you've maxed out that eclipse.

Go feral druids, they are awesome. I am so impressed with my lvl78 cat, she is outdpsing my rogue and paladin by 2 fold.
