Disclaimer: This is just a suggestion.
Hey guys, I think that somewhere in the future Blizzard should add two new classes.
1) Wizard: Just like Hunters utilize bows/guns/crossbows as a main weapon, Wizards will be able utilize wands! (don't know how that might work though...again, just a suggestion)
2) (Haven't thought of a name): This class will be able to amplify buffs from other classes. For example, a shamans Totem of Wrath gives around 200 sp. But, this unnamed class will gain about 4 times that i.e. 800 sp. So this class will shine in raids, don't know about pvp though.
