The Fighter does his job efficiently and effectively while *feeling* like a Fighter. He deserves top two.
The Rogue does his job efficiently and effectively while *feeling* like a Rogue. He deserves top two.
The Wizard is a little tougher, since his at wills aren't as controllerish as the other controllers. On the other hand a controller seems to have two purposes- impeding enemy choices, and dealing area damage. The wizard is the king of the second. No other controller comes close. He deserves to be in the top three, but no further because the competition from the Fighter and Rogue is too strong.
The Sorcerer is just a blaster. And a boring blaster. Its like they took a wizard, removed the controller bits, shrank all of the area of effects down to match the non wizard controllers, shrank them again, and then increased the damage by means of a damage increasing mechanism that is completely bland, vanilla, and tactically uninteresting- a flat +X to damage. He should have been voted out before the Barbarian, which is at least a tactically engaging class. Vote Sorcerer!
