HERE "Q: How does the new keyword “Remove” come into play with the Advance and Cover mechanics?
CG_ParkingInstructor: We’ve used dispel in the past for characters that need to remove debuffs but General Skywalker has the special keyword, Remove. This will remove all status effects, including un-dispellable effects. This was necessary for the mechanics of General Skywalker’s kit and given the legendary nature of General Skywalker’s abilities, we felt it made sense in this rare case but this is not something we plan to use in future character kits."
