I don't know much about Macro's and Optimal DPS and all but I have to say this to OP.
I was about to say for people to chill a bit because I thought you were new, until you said 'What makes you think this is my first account?'
Well firstly, you're posing really bad information as people are responding too.
Then secondly everyone here has pretty much told you you were wrong and you're telling us how to maximize
damage at when your first begun this post, was level 52...Instead of taking everyone's advice, you actively beat people down and the nicest one person to critique you was Kitfox
and you pretty much tell her off. People main these DPS and do savage content
so they aren't trying to be buttheads but trying to help you.
Try and learn from others advice and stop TRYING to play poorly and grow.

TLDR for people reading this: DO NOT USE MACROS IF YOU WANT TO BETTER YOUR DMG.
