Charm has a glitch where a player either cannot break free, or has to wait until they walk around for a while before the break free happens. This skill favors the CC animation completing over the break free of the player affected. I can start to spam break free even before the Charm hits, but I still have to wait until part of the animation completes. I know I am not the only one to experience this. Stacking additional CC effects on top of it only compound the issue.
