a MMO is often not as smooth as a FPS or some other game where multiple functions can be initiated at once. They want you to take into account having time delays and limitations like GCD's, and obviously they want animations to be accounted for as well. I dont really see the issue there, its just you wanting to do things faster..well you cant, so work with what you can do. This is not a fighting game or an adventure game, its a 3-d simulation of a tactical turn by turn game and thus your abilities are locked down within an economy of of gcd's, casting times and animation delays to represent turns. Otherwise everyone would be leaping and casting like flying light spawning monkeys from all over the battlefield.
