A lot of people point out that Shadowy Disguise often ends abruptly, but is this a bug or does damage from enemies cause this to happen? I don't notice it often at all in PvE, where enemies stop attacking me the moment I use the ability, but it happens way too much in PvP, where enemies can keep swinging.
I asked this a while ago and no one responded at all. Surely someone playing the game must know the basic mechanics for this ability?
