If anything it shouldn't be macro. It should be say or party chat only during combat. If it's urgent enough for someone to type it out in combat, it's likely important enough to not be 'spam'. I just had a nabriales fight that went terrible on the orbs phase and got LB3 early for it and as a tank I was begging the party to LB the adds but I was ignored as the terrible dps failed to DPS the last add on their own.
