So then BT, what about all those shooting games out there that are all or mostly about memo attacks? Are they inherently unfair by your reasoning?
Memorization-based attacks, be they completely static or rooted in aiming, are a longtime staple of shooting games. To say that memo attacks do not fit into these games is just plain incorrect. The kind of problem solving aspect these attacks bring to the table is really no different than, say, figuring out how a platformer boss' attacks work, where you go "Okay, that method didn't work, let me try something else next time". There's nothing "unfair" about this kind of challenge, as far as I'm concerned.
And I have to disagree with the "automated machine" comparison. If you figure out an attack, practice it some, and then start becoming that mindless in subsequent attempts, you arguably leave yourself more open to messing up at inopportune times. Muscle memory is powerful, but not foolproof. If you ask me, being able to recognize what you're doing as you're doing it and not have it affect your game (essentially, overcoming the "centipede's dilemma") is what allows you to become truly consistent at something.
