I am a casual player. I I can do it, anybody can do it. I'm afraid and disappointed to seeing how much more simplified controls are getting for gaming. This doesn't just apply to fighting games. What's the point of even playing games if you want everything handed to you.
I still have problems with HCB inputs in BlazBlue and it sucks when characters I want to play have them as command inputs. I don't think you're as casual as you think yourself out to be, especially compared to the fighting game layperson.
Incidentally I don't have any problems with tilt attacks in Smash, but I've also played Melee for way longer than I have any SF-derived fighting game.
I also don't see how simplifying inputs leads to games playing themselves for you. What do you think about autocombos in P4U and UNIEL, for example?
Without execution requirements tons moves would be broken. Many moves have the properties they do because of executional demands.
You should not hide move properties behind dexterity requirements full stop. Using executional demands for things like DPs is fine as long as it doesn't conflict with the first.
