Some moves interfere with eachother like: skills automatically overriding inputs by flowing into other skills, and awk / pre-awk skills having overlapping inputs.
Then thereother cases where some classes automatically go into q-block after any movement skill.
Letting us put skill toggles into quick slots would be a great QoL update and could bring new strategies in PvP and PvE.
Bonus: Also maybe add a "lock once" feature so you can have less toggles to keep track of.
