Genji is not rewarding enough?

I've played overwatched for a bit now and genji seems to be the most skill-dependent hero in the game

Genji can perform really well in the games but this requires a fair amount of SKILL + EFFORT, while other heroes can perform the same without any effort at all (looking at you, reaper)

I mean for real, I can pick reaper and jus run around left clicking and then pressing Q to get 5 kills with ease. Genji can't do anything like that without sweating like a bitch

so: genji:high effort - high reward reaper:low effort - high reward

that just doesn't seem right to me, i suppose the heroes which require more skills should grant more rewards if you play them really well

at the moment you should get hours and hour of experience +skill with genji just to perform as good as an average nooby reaper
