A good thing to keep in mind as well in conversation about button bloat is "how many buttons can one comfortably reach?"

Personally speaking I keep mounts and miscellaneous things on non-combat crossbars (the default crossbar called when I sheathe my weapon) that are cross-mapped to every job.

I also have sprint mapped to my L3 button. So on controller I have access to 8 face buttons with four modifiers: L2, R2, L2+R2 and R2+L2. 32 easy access buttons dedicated to any job I desire. I also have it set so I can tap r1 to swap to an entirely different crossbar, giving me access to 16 more buttons for 48, though some feel more at home with R2+R2 and L2+L2 giving +4 buttons each for 40.

With that said comfort is key; of the 8 face buttons, only 4 can be reached comfortably while also being able to move due to the left thumb managing both the stick and the d-pad. All 8 *can* be reached with flexible hands (the Monster Hunter Claw) but even that can make precise movement difficult. So a controller player is smart to put frequently used actions on ABXY over the d-pad.

So even on controller there's still room for more, especially considering what Sebazy said in useless or niche abilities just straight up not being bound at all. Should we push to hit that limit? I'd argue no, but also that we're far enough from that limit that its fine as-is.
