I play on controller and have easy access to 3 Cross hotbars without using the "switch to another hotbar". You can set them up. If all controler players would just take 30 minutes aside to look at the options...

But how many buttons are 3 cross hotbars. One is 16, so 48. Yep. 48 WITHOUT switching. My limit button isn't even on there ^^. Easy space. If you want to know how many are displayed without pressing a button (for info on recast) the answer is 2 bars, so 32.
