I'll have to agree with Daniolaut, I use a gamepad on PC and have yet to run into button bloat issues. Almost all of my jobs fit onto one crossbar + expanded crossbars, even Sch and I don't run into issue of mixing healing/dps utility.. I have enough space for everything to be neatly organized.

If you're playing with default gamepad settings though it can feel extremely limiting, I have a lot of filters on for combat/non-combat, for targetting and crossbar rotation as well as some crossbars that don't show up at all unless I use R+Dpad. There are a lot of tools to customize gamepad to your playstyle, just need to mess around with them a bit.
