On controller, it’s difficult to have fun with the perks such as Zenyatta’s Ascendance perk and Sigma’s Levitation perk, as while you’re pressing and holding the jump button to hover, it’s nearly impossible to also turn while doing so with the right stick. Adding a toggle in the controls - Hero and HUD menu would help tremendously, like for other similar abilities that already have a toggle option, such as Mercy’s or Echo’s toggle descent ability.
The clawing method enables a great many things to be possible. I am glad I learned it from some past games.
