I like pressing a lot of buttons. I also like pressing less buttons.
It depends on what the buttons actually do, though.

Personally I think ability compression is a better design if done well.
It leaves room for more meaningful buttons instead of spreading a single combo out across 3 of them. I do not care if the combo becomes a one button combo. It does not actually change anything. It is not more skillful to do a 3 hit combo by pressing 3 different buttons instead of 1.

It does have a different game feel, but you can get the same game feel or better back by replacing those combo actions on your hotbar with new shiny ogcds and such. Granted they actually have to give them to us.

My addiction outside 14 has always been high execution fighting game stuff. I love, love pressing a lot of buttons, and doing motion inputs. I also think games with one button special inputs can be just as fun and creative to play, just as stimulating. It's different, but it's not worse or better. It's just different. And it's just the input phase of the game. The game is way more than pressing buttons.

Ideally 14 is testing your movement, resource management, team player awareness, environmental awareness, etc while also seeing if you can keep your GCDs on time and weave oGCDs correctly while understanding your job and role. Compressing abilities onto less buttons should not be seen as a demon taking away player expression or skill.

But the fact you feel threatened by that change should make you realize how little actual player expression and skill was left if you miss what is seriously just button bloat pretending to be an interesting rotation.
