Shamans will not be touched by Melee at all during 3.2, because there is the earthbind totem, and in GW, not being able to go slower than normal walking speed (warriors Hamstring is annoying as fuck) will give you perfect ability to avoid any melee classes, aswell as those pesky hunters and their Conc and Wing Clip. Shamans also have the higher armor value, and generally more health, even without a shield.
