There are lots of tricks to make the cross hotbar infinitely times more efficient. Having only two bars accessed with R1 when your drawn is, in my opinion, the weakest of the upgrades to the bar situation simply because R1 responsiveness is pretty slow on the ps4 for some reason. The R2+L2 combination bar made life a lot better when it came out. I think my favorite quality of life trick I found is a lot more involved. You need to use

/crosshotbar copy [class/job] [bar number] [class/job] [bar number]

without the brackets. For example

/crosshotbar copy drg 1 lnc 1

That will copy the first bar from drg to the first bar of lnc. Now with some work, you can save two different bars from dragoon on to two different bars from a crafting class and then make a macro to switch those bars back and forth. It is faster than hitting R1 as a cycle method because you don't have to release R2/L2 to get access and you still have the ability to use the R2+L2 combination for other things (I use them for defensive moves on my dragoon.)
