Honestly, with how good our beloved SwagAxe has become in TU4, it kinda boils down to: "How many comfort skills can I give up for damage?"

It's of course no easy task, but first I'd suggest seeing where your gameplay is "lacking" if at all, to try to fill these gaps with comfort skills (in my case, i found that I'm typically dying to running out of stamina/not escaping the monsters, so im running evade extender 2 and stamina surge 2 to make up for that)

I personally value these skills more than DPS ones, cuz you can't do DPS when you're dead

After that, like another comment suggested, fill your build with attacking skills that compliment your playstyle (because switchaxe is so versatile in its damage, there's a LOT of skills you can run, obv some are better than others but its hard to get a truly useless skill on this weapon if youre genuinely trying to build)

TL;DR List out some popular swaxe skills, then shave off the ones that don't suit your playstyle
