So, as I run away from attacking guards and/or players in PvP and cast Retreating Maneuver (mine happens to be III) and if I get hit with a snare or immobilizing effect, even though I should be immune to snares and immobilizations as per the Retreating Maneuver that I cast within 5 seconds (duration is 32 seconds) I cast my Extended Ritual (which is IV for me) and it wipes not only the immobilization or snare, but it also clears my retreating maneuver. Is this intended or a bug?
