I'm on PC, but have always played with controller. I have two active cross-bars. in Character Customization, in Hotbar Settings, in Custom I have "Enable customization for when weapon is drawn", so I only cycle through the two hotbars while fighting. That's usually enough for most of my classes. Interestingly, SCH (which is my main) completely filled both my bars, so I moved Selene/Eos to a separate Hotbar that I can click with the mouse (or virtual mouse) when I'm not in combat. I'm probably going to move the LB to that Hotbar as well cause I just don't have space for the new two SCH buttons we know we'll get. I'm still going to be short of one button, so I may macro something like my Swiftcast Res, which I'm trying to avoid so I may look for something else.

Other than SCH though, the two-bars have (and are still enough) for my other jobs. Having the single tap between two bars makes gameplay rather nice.
