I've spent the last year defending this game from people who instantly write it off as shit because it has a new system. I think the name is dumb I haven't written the game off. If I wanted to critisize it instantly I'd say something much dumber then "The name Mist Knacks sounds stupid".
I am aware SE are using different names, but Knacks sounds...childish and so not...powerful sounding, like the best attack you do is KNACKS!
It's just one of those things you can complain about without it having any baring on how you'll enjoy the game, like in FFX Tidus looks like he was dressed by 3 blind people and runs like he has a stick in his ass (and FFX is one of my favourite FFs). No harm no foul.
