Is Shaman the BEST all-around class in the game?

[WarpathEQ]

I would consider Bard the best all around class as they can do a little of every single thing that other classes can just not as powerfully, they are the only class that can truly fill any role to an extent.

Shaman is best in game in certain situations like 1v1 soloing the toughest mobs in game. Slowing high end mobs, resist debuffing, and melee buffing.
