the GCD is a non issue, and the cast animations are a non issue, learn your class, and/or ask for tips, and stop your porn downloads to fix lag. If ppl are dying because you had to move and were GCD'd, heal them earlier or let them know "hey, you know if you stand in that brown circle there, you take alot of damage, so pls dodge it"

And if "memorization > skill" in this game is the game, imagine how many ppl would bitch if SE set phase 5 to a random rotation if ppl can not master memorizing things.

but its sounding like, mujen, maybe this isnt the game for you, there are others out there.
