Okay, you sit down for a D&D game at a con. The DM lays out a set of pregens. There is one of each class available. You are given first pick out of the entire lot.
What character class do you choose?
Personally, I would pick the fighter. While I have gone on in the past about my love for the class, I also like fighters because they are the easiest class to play. There are no fiddly bits like spells and thief skills to worry about. And no matter what type of campaign the GM has in mind, the fighter fits in like a hand in a glove. Even in a game that is non-combat oriented, there is still an advantage to having a strong, intimidating figure around.
That's my choice, what's yours?
