I'm currently playing DA:O, and I'm not certain about my party. I've been switching back and forth a lot, which I really don't want to do, and right now I have Alistair, Morrigan, and Zevran, and I feel like this sucks. Wynne seems like a better mage, and I don't know what to think about Leliana. I'm facing some indecision.

What parties did everyone use in this game, and why?
