Spent a few minutes screwing around with Brigitte. She's surprisingly fun - the best parts of Reinhardt and Torbjorn. She's got a little 600hp shield and she can do a shield bash while her shield is up; her primary weapon is a flail, which she can swing at just beyond melee range or throw on cooldown with a range that feels like Roadhog's hook. She can toss healing packs whose overheal grants armor, and she does radiant healing by doing damage.
