How does Global Cooldown works?

Can someone please explain we how this works exactly?

Is it some kind of server timeslots?

Or is it a waiting time you have to wait after each Ability?

Or only after instacast?

If I cast a 1 second ability, do I have to wait till the end of a gcd that has started at the beginning?

What if I cast a 3 second cast?

I'm trying to sort this kind of simultaneously kicking dots. But gcd seems to be an important part in it.

GCD is a cooldown that activates between abilities, I think it's around 1.15 seconds on this server. Anyways, it starts at the beginning of a cast, so if a cast is 1 second long, it more or less removes the whole GCD. So if you cast for 1 sec, you can cast an instant spells at the same time the 1 sec cast ends. Instant spells on the other hand trigger the GCD, and you have to wait for the GCD to end before casting the next spell. So in other words to get dots to tick at the same time, you basically have to cast the dot with a cast time 1st, then an instcast one so they hit more or less at the same time.

Thanks for the answer. That is how I thought it would be.

What is with 3 second cast. Do they eat up one gcd or two?

Since the gcd is 1.15 seconds afaik, 3 second casts eat up 2 gcds. Which means that during that time, you could've cast 2 instant abilities.

Spoiler:
A cast triggers GCD, means you still can cacel your cast / channeled ability, if you do so while you are still on GCD you can simply do nothing.

example:

>casting generic fireball spell
>stop cancel after 0.2 sec cause I have to move or something
> 0.95 GCD left, can't use spells that are on GCD (usually other casts, instants, what ever)
>GCD is off, can cast again, throw instants etc.

So a 3 sec cast triggers the same GCD as an instant, it just has a 3 second cast time.

hope that was understandable with my pleb english.

that's at least my understanding of it, which I believe is right. :D
Edit:
wrong. :D
if you cancel a cast GCD gets reset.
the more you know. :>

Has nothing to do with DB work. I hope that helps your concern.

Maybe in addition a quote from the good'ol Azarael on the topic.
Azarael wrote:The GCD on both AoR and RoR is 1.15 seconds. We know this is the case because the client allows abilities to be used 1.15s into the displayed 1.5s GCD as long as you get your timing right. If you invoke the ability too early, it will be blocked until the 1.5s GCD is up.

We previously had the server enforce the 1.5s GCD hard, and it resulted in client casts being cancelled.
On a side note there are several abilities that dont invoke a GCD. Like stance switching for marauder/SW.

As an NA player I have to live with the knowledge that latency between my client and the server make my instant casts abilities sometimes take 3 secs to fire off.
For a melee player its a nightmare :D. My fingers get raw from slamming my poor keyboard to death.
