I just started it up again for the first time in about two months. I've got all the characters from the first batch, but only the ex-cerberus vanguard so far from the most recent two dlc's. Wasn't super impressed, seemed like a less abusable human vanguard. Seen a bunch of people playing some of the new human folks, but I'm not really sure what they all do. Do want to try the infiltrator- it seems to be like Kasumi from ME2, with Shadow Strike and cloak as abilities. Guess for now I'll just keep rolling with my krogan vanguard, drell adept, and quarian engineer as my base classes.
