So long story short, putting gcd on la the way zero suggested would cause us to press 1 2 3 over and over until we run out of resources and have to press our mouse button to restore them.
What a load of ***. Just please.
Wow has a completely different type of combat with secondary stats and a lot more abilities, and also cds, eso does not have that, remove light attacks weaving, animation cancelling, etc and we get the worst combat system of any mmo.
