I pre-ordered as soon as I saw they used a Lamborghini Aventador as a promotional piece
No regrets though, the beta was incredible. One of the best shooters I've played in a long time, and much more interesting to play than cookie-cutter games where the only real variety is 'class'.
Favorites are Mercy, Reinhardt, and 76 actually. I like 76 because usually if I don't play healer no one does, and with him I can just heal myself. So can Roadhog but I despise Roadhog.
