I've been thinking about one of the complaints I hear semi-regularly, that the combat controls aren't fluid enough, that they feel laggy. Any chance this has to do with the ability queuing?
I remember finding the setting almost immediately when I first started playing the game, so responsiveness was never an issue for me. For players who've only trialed, or are trialing now, were you aware of the adjustable ability queue timing in the settings?
Under Settings- Actionbars - Ability Queue: None/Short/Full. By default it's set to Short.
It's mostly for anti-spamming, but could directly affect your split-second decision making while fighting or healing.
