If I have to toggle between 3 skill bars using a controller, that will probably be the point I can no longer play DPS. I might still be able to manage it on tank but the stance dancing may become more difficult. Healer would be ok.

I currently use bars 1 and 2 along with half of 8 for L+R. Tried using the L>R and R>L for a full extra bar set but I would mess up frequently and press the wrong one first so I'm sticking to only L+R for an extra half bar.

Not sure how many skills that is total but if it absolutely comes down to it, I'll end up combining certain skills with macros to conserve some space probably wherever possible. I just cant do keyboard on this game, which is strange cause I used keyboard on ffxi but it probably has something to do with how often you have to press buttons in comparison. Controller is more comfortable and manageable due to essential tremor.

Went ahead and counted, 2 full skill bars and a half on ps4 controller is 40 slots. Guess I can't handle any more than 40 but I like to add a mount and a potion slot in there so thats 2 that can be removed for skills if completely necessary.
