You already displaying FG/SA/Iframes, what stopping you from displaying CC imunne status ? Everything works as intended right ? There is nothing to be afrais for, players don't start to report massive stunlocks while CC immuned, right ?

Bring this to players.

id like also to see when i fail because I missed or because enemy resisted

I once suggested that they should change from "immune" to "resist' when it fails due to resistance, but...

The FG, SA, and i-frame go to the skill in PvP factor.  Now showing a difference between immunity due to CC limit and resist due to RNG should be displayed.
