The tooltip on rapid manuever says you lose the buff if you attack someone. Currently, in pvp in the thick of battle, I do not lose the buff while healing, sprinting, purging, dodge rolling etc. I do lose it when I attack someone, as intended.
My issue happens from activating my Nightblade ability dark cloak. It drops my maneuver buff. This happens when things go south (pvp or pve) and I hit Rapid manuever then try to speed cloak out of the area (Concealed strike gives an additional 25% movement speed as well making this very good for survival). Is this intended? Sometimes I dont lose my speed buff but I'd say 90% of the time I lose it if im in combat.
