Hey :)
I am a long term CS:GO player. In almost every game, I have ALWAYS used scroll wheel to jump, but along with that, also have it on space bar so the option to jump normally is still there.
I feel this would be a great feature as in SoT as there are many things you can set binds too, just think of how many items there are in the radial menus.
EDIT: Just to be clear, when in PvP I for some reason prefer scroll wheel as I feel like I have more control over my movement, when not in PvP I prefer space bar, hence why having an option for both in SoT would be great as there's both PvP and PvE
