Mercy, and she does a pretty good job because she likes to be properly appreciated (not that people always do, but she feels really good when someone comments on it.)! Also always uses the Witch skin, she grinded like hell for it in the halloween event as soon as it was revealed...
oohhh these are the most adorable ideas, especially the roadhog one!! youre totally on the ball with the mood of her not always being super aggressive/competitive and liking being playful at times, haha ♡
