You guys need to learn how to optimize the cross hotbar better. You can play nearly every job with 1 bar and the combo bar without having to use stupid macros that grant you "efficiency" but actually only make you worse because of how horribly designed the macro system is. As a tank I suppose it doesn't matter too much, but a DD is only losing potential dps with all their buffs on one macro or multiple weapon skill macros.

My point is that if you optimize the cross hotbar correctly you can have plenty of space for your jobs x-potion of choice.
