Present. I hate it but for me it's too many skills to use keybinds for, plus old MMO player habit, so eh. And I know many others who do the same.

To OP, kudos for all the effort. And don't listen to people telling you to use controller or bind differently, whatever works for you is good. Each person's hotbar layot and keybinds tend be very personal and not make sense for someone else, but it's you it needs to work for, not others.
