Tiers?

[Spuddles]

Just because blasting isn't as good as the wizard's other options doesn't mean that it isn't good.

Amen.

The wizard is tier 1 because he is theoretically capable of "breaking" the game (taken here to mean: solve an inordinately large comparison of challenges compared to what other classes are capable of solving, and/or drastically shift what kind of challenges he can solve on a day-to-day basis). Just because he chooses not to (or does not realize that he is capable of it) does not mean that the class itself is diminished.

Just because your wizard doesn't "break" the game doesn't mean that the wizard class isn't itself "broken."

See my edit.
I'm in favor of moving classes up tiers, because hey, internet + discussion = more from less.

Nowhere have I claimed wizards aren't broken, but to break them, like any other class, requires a certain level of system mastery and optimization.
