What was your favorite class?

[Curmudgeon]

I personally dislike Rogues, but they are the quintessential skillmonkey, they're pretty simple to build and play ...

The bolded part is entirely wrong. Rogues may be the single most complex class to build and play effectively. I usually require a couple dozen sources for a Rogue character. WotC did a poor job of creating the Rogue, but provided solutions to most of the problems; it's just that these solutions are scattered across many supplements.

That complexity is why the Rogue is my favorite class.
