No, but I think the start up animation and the rocket speed should be quicker. So if you do miss, yourself back in the fight quicker and you can hit things easier.
Yeah sure, but Genji should also be able to deflect him mid charge to send him back to his team, with no possibilities to stop the charge after deflected
If a rein does a bad charge he deserves to be punished. He shouldn't be able to just cancel it, like if he accidentally throws himself off a cliff, thats his fault.
