I've noticed, as well as others, that the macroes have a long time to execute once you tap whichever you want. It's almost as if when you, for example, hit your stun macro, there's a wait 2 before it casts.
wait dose this happen to all the macros seeing as if i have a late vok it is the difference of life or death with my class.
edit
btw for everyone saying things about macros it just sounds like it is lagging or a glitch best idea i can come up with is give it sometime and if something is really wrong se will get around sooner or later to fixing it.
if something is really wrong best thing u can do to make sure se knows is submit a ticket with them to let them know that there is something wrong with what ever system
