Maybe , maybe not. Honestly, everyone is going to do it regardless of the devs wishes. Unless they actually ban everyone who does it.. but I doubt that, because they probably wouldnt have many players left.

I have yet to talk with a single guild who is not supporting macroing at least in private.

If the devs make the catastrophic mistake of banning macroing, and not banning everyone who macroes - then your going to have a huge disparity in power between those who macro and those who dont.

Banning macroing in a game like this does not fix the game,
it creates an artificially uneven playing field between those who macro anyway and those who play to the devs wishes.
