Sorry if this has already been asked, but search is disabled. So, I've noticed the Ability Queue, and also noticed my game seems more responsive without it, even when I set it to 250ms, which would be very close to my latency (180ms).

How was this supposed to be used? Is it to be used by someone who might have latency spikes instead of a constant latency? What I feel when I turn it on is as if my latency just got the Ability Queue amount added to it ... randomly.

I'm asking because it seems my game already takes my latency into account for the cooldowns. They start as soon as I hit the key. Is the game working correctly without the ability queues, or am I missing 200ms of DPS every GCD, which could be done with the queues as I'd have a bigger window to press the next button?

On other games, usually the cooldown starts to count when it receives the "ability used" message from the server, so I'm kind of used to pressing things before they should be available. Is that not necessary here?
