The nin on my alt has 2 full hotbars, but since most skills share CDs, I don't have an issue with it (skills on gcd and trick/sneak attacks). But, my main, a pld, uses 3 full hotbars, and I still have no issues, while 3 hotbars is excessive, I have every skill, a ready check, ABC marks, Mark #1, sprint, cross-class, repeated RoH on hot bar 1 &2 all defensive CDS set to hotbar 1 and the hidden hotbars (#3), so I have literally everything mapped out, and I remember it all perfectly. It mostly just takes time to get used to it and to get familiar with your hot bar layouts. And, yes, I do play on ps3 an alt account for making money on a different world. If I can't travel with more than 1 mil, I'll make money on one, buy stuff, world transfer, and re sell it on a my mains's world. Easy way around the gil limit. And play on a ps4 with my main
