Beta changes for Druids and Shaman

Some class changes are coming in beta - we should expect to see a lot more of this as this is the purpose of a beta testing phase. Spells, talents and abilities will continue to be changed and tweaked. Her are the ones that are affecting the classes I have been playing. (source - MMO-Champion)
