I am aware of how the game currently works which is why I am requesting this change! And I believe it is not a major change at all

At the moment, as you said, when I execute a macro, each line is sent to the server one by one, they could change this so that when you press your macro button, the whole 10 statements are sent to the server in one big string, then have the server break this up into commands, validate and execute them... and that whole round trip would take no more than 2 secs for the user, 1 blink, and 10 lines executed
