I set up the weapon swap to a single button for swapping between weapons. the issue is its very clunky and not very consistent with swapping the weapon. You will see the highlight for the weapon swap, but many times wont actually switch. This can be a problem in combat.
The only way around this is I have to keybind the weapons separately. I really want to put this onto a single button press instead of taking up a keybind slot.
Agreed, though the issue is due to there not being skill / key queueing. If you weapon swap while attacking or using an ability, the weapon swap does not register. It will only register as an action if there are no attacks or abilities happening which leads to downtime while you avoid doing things to swap weapons.
Also binding it to some keys works fine, others not so much. My swap weapons is scroll down, that seems to work ok, even in combat. When I change it to Mouse5 (side mouse button), it gets buggy like described above.
