every single class can fit in 3 hotbars, imho. i used to use shift+ctrl+alt, with 1-5 and a few letters that i forgot, but now that i have an mmo mouse, i use shift and ctrl with 1 through = and have even less issues. in fact, im working on taking my entire hotbar setup down and squishing sprint, tele, return and a mount onto my 3rd hotbar and going fully 3 hotbars (right now i have 3 battle hotbars and 1 shared hotbar that hosts that and a few other misc buttons)
