I've just been picking whatever role the team needs, and 9 times out of 10 it's Tank or Support. I've found Defense is never lacking for picks, which works for me since I prefer the Offense characters.

Played a ton of Zarya and Mercy yesterday (first time using either) and yeah, these two are beast. Zarya's tough on pubbies though, because it's difficult to coordinate her super when your team doesn't talk.
