Sorry, but if 2 seconds are not enough for you to press a button, than you have to put up with people calling you slow. No way around it.

If you really are better with that macro, thats fine, you seem to be able to clear stuff you play, all power to you, but it's very very far from optimal.

Can you tell us how you came to the conclusion that your macro does better DPS for you than manual play? any numbers? That'd be very interesting now.
