Psh, Engineers.
Had my first all-Adept match today, FBW Reapers. I was a Drell, one Asari, one Justicar, one Human Sentinel, which totally counts as an Adept. Never before have I seen things die so quickly and so horribly. Spent a couple of hours playing Reapers with them, was pretty fun. Wish all my random groups were like that.
