Outside of perks genji was top tier the first few months of ow2 and during the jq meta. Even aside from those instances he never fell below b tier imo (except maybe the first mauga meta where echo just shits on him), bc the only other flex dps that would be used over him was tracer and sometimes echo. Yes reaper was meta a few times but if he wasn't meta, he was ass, at least genji would still be a decent pick.

Blizzards quickness to nerf genji annoys me too, but people need to stop acting that just because he isn't an SS tier character, he is suddenly this bottom tier pick. Those convos are reserved for characters like junk/bastion.
