My core hotbars stay the same, I rely on muscle memory for a lot ahah. Biggest change I do is when I'm done leveling a class I strip it down to the barebones needed for my rotation and stuff in a trial. IE Smn went from needing 3 hotbars (barely... I just needed consistency for role actions ahah) to needing 1 hotbar for the rotation and one hotbar for summons.

But I do regularly change up my menu macro!
