I'm personally going to go with 5x druid and 5x lock for a 10 box BG setup, it will have GREAT DPS, as well as pets for some added "point and forget" DPS. With 5x moonkin, you can still get 10x rejuv on a single target, or roll up to 10 on every target for aoe healing. Imagine just hitting a healing button as many times as you need for aoe healing on your team. Taking a little bit of dmg? hit your rejuv macro once. more? hit it two or three, and with a good setup, you will stack the rejuvs up as long as you want. With the teams mobility of doing almost maximum DPS while moving, as well as healing... it will e a very difficult team to stop in BGs. Innervate as well as lifetap means you wont run out of mana as often.

I'm excited about it
