I have some Hotbar setups that aggressively use WXHB for rotations. I'm starting to (very rarely) have some issues opening cans or using housekeys because of the way my fingers are used to moving and curling playing FFXIV.
Suggestion: I play on PC with a Dualsense controller. Why not use the shoulder buttons to mimic the 'Gamecube shoulder click' to set off the WXHB?
Just a feature I'd like to see, throwing it out there.
