Where are all the skills going?

Yes complexity is being reduced, they've outright admitted as such trying to streamline the game.

That's only sort of true. It's less about reducing complexity and more about reducing ability bloat. Even as far back as HW people were complaining about there being too many buttons and running out of hotbar space (e.g. on DRG the main combos alone take up almost an entire hotbar.) It's easy to talk about skill removal as SE trying to 'dumb down the game', but there's a middle ground between pressing 1,2,3, repeat, and needing 20 different buttons on every fight.
