Weakest class, What is the weakest character types in the game? Options

[Ryel ril Ers]

The topics a little bit strange, but i want to hear pros and contras of the "weak" classes.

One: The players see what are the worst choices, and which character better that position.
Two: There are nonliked classes and i want hear that they are really useless.

Too early to say anything, but the thief/cleric is a potent class, but they have a big disadvantege:

The thiving button is in the special ability groub because it is replaced by the turn undead button.
