i use 3 hotbars and im kind of fine. the first is full of heals and eos abilities. the second is dps, and the third is the rest with ressurection, all summons, macros to obey or to sic, mount and everything. normally i dont really have problems to heal anyone on time, im quite quick on scrolling with dpad through party.
but its all up to everyone
the only thing that i dont understand is people who make those long 5+ second macros.
