I think I've figured out the source of 90% of my wrong keypresses.

I have 12 classes at 70 and have never used one of those horrid things. the GCD is just long to the point of being off putting.

Iirc, there was a pretty decent size thread on this in late-Heavensward that boiled down to weighing one's ability "to losslessly double-weave" against one's ability "to feel as if the majority of GCDs experience no deadtime", or essentially looking for a suitable compromise or equilibrium dynamics in button-flow, and seeing how we can cheat that compromise slightly for mutual benefit to either end (such as by animation times scaling with one's GCD, as not to create a point at which double-weaving is no longer possible just by nature of your class or buffs).

My memory's thin at this point, but I think those staking their hope as to an improvement more or less figured the best would be the lowest base GCD which still, with scaling, allowed for standard double-weaves without loss, perhaps making use of slight toolkit reworks towards more later-available tools such as those afforded by (job gauges or) proc mechanics to better fill our time between bursts without destabilizing the general macrorotational flow or rhythm.

Maybe this game isn't for you then. I certainly found the gcd very jarring at the start but I got used to it and at higher level you end up filling that time in the gcd with ogcds or dealing with boss mechanics. If I have any problem with the rhythm of combat in this game, it's the server ticks. Sometimes they just work against you and you can't do anything about it.

The inconsistent snapshotting types and norms are my first, here. The global ticks, and how a buff that seemingly was up with a second to spare before the global DoT tick mysteriously fails to benefit it, come in just behind, though -- largely in combination with snapshotting.
