I'm in the process of climbing back. I lost a lot of SR playing with IRL bronze friends. I play Ana, Moira, Lucio, and Zen depending on map and attack/defense. I don't play Mercy, but she'll be nerfed soon (luckily). I just find Mercy boring personally is all.
My ID is currently DapperHound#11175, but I'm getting a name change soon. So if that doesn't work, let me know.
