I’ve looked in many places, couldn’t find any answers.
To make this clearer: I want to change Junkrat’s RIP-Tire detonation keybind, which is R.
I play with the talent that allows both ultis, and I almost always end up casting RocketRide just after I detonate the other ulti. Or enemy quickly destroys the tire and I still end up pressing R in that moment, also end up casting RocketRide.
