Would be it be wise to use a Balance druid? Im hearing that its good and then bad, i know im loosing some good things with a shaman, but is it really worth it to drop a shaman for a balance druid in the long run?

I ask becuase i have a 70 druid on my main account thats not being used and i was pondering respecing him balance and moving him over to one of my slave accounts.
