If you're gonna raid as boomkin, then you really wanna drop pretty much anything having to do with feral.  Something like this is what I run for raids  http://db.vanillagaming.org/?talent#0tTxhMEskZxVc  You'd really have to drop feral of any kind for it because your GM is gonna be pissed if you don't have improved MoTW.  The nature's grasp still allows for evasion from melee, but I admit it's still nowhere as good as feral charge, but that's the price you pay.
