I could then COMFORTABLY execute all 4 skills in my predesigned desired order, without breaking my wrist trying awkwardly reaching and stretching out for ctrl/shift/1/2/3 keycombos,
just because the devs delusionally think "that makes the game better durr". We're not all guitar/piano playing nerds irl with girly bending fingers okay? This is literally painful and stupid.

Sounds like your problem is actually the button bloat , too many hotkeys for all the abilities that ciould be reduced by combining certain combo actions.
Unless youre using a combo plug-in and some macros (which isnt ideal in combat) there is no way around that.
Ninja is one of the most bloated Jobs in the game right now.
