"Mcree you just have to right click and stare at the enemies chest"

You can say the same of genji, right click and stare at thier head or chest and finish with a dash which is now reset due to your kill

Yes aiming may be harder but thats not the point, the point is if your good with genji you can do the exact thing you claim would be "op" in mcrees hands

If you drop behind a team, the second you kill one of them they will all notice you, genji is far far harder to hit than mcree, if you drop down and kill thier healer you can bounce around and kill any other non tanks while they desperately try to hit you

With mcree if you drop down it doesnt matter that your one kill reset your roll, that roll wont save you from a whole team unlike genjis erratic jumping while outputting dps

Genji is ridiculously op while mcree is literal dogshit right now and thats coming from someone who mains him, letting his kill reset his roll would at best make him do a little more damage to the enemy team considering his ult is laughuably useless against any enemy with half a braincell and his flashbang works like 70% of the time
