Neverwinter Nights 2: Obsidian Looking for Wizard Input

Rob McGinnis and Obsidian Entertainment are looking for user input with regard to the Wizard class.

I wanted to take some time to get some feedback on the wizard class from you all. Some people say it is too weak, others say it is too strong. Why is it your favorite class? Why do you hate the class? What say you?

(Note: Please keep this discussion about the wizard. It's ok to mention other classes for comparison, but be careful we don't get too far off track)
