Why Pokkén Tournament and Pokkén Tournament DX should not be just like Mortal Kombat?

Hey, guys. Did you know why you think Pokkén Tournament and Pokkén Tournament DX should not be just like Mortal Kombat, including all Burst Attacks replaced by Pokétalities^*?
^*_{The term "Pokétality" is a portmanteau for "Pokémon" + "Fatality".}

I'm not sure what you're going for here - "did you know why you think" ?
Is that what you think? If so, tell us why. Or are you asking for our opinions?

Keep in mind, MK games are gruesome, bloody and most violence of all fighting games if Pokken tournament have fatalities that would simply raise the esrb rating to T or M, and all pokemons games are E rated and the pokemon company keep likehood of E10+ and E rating.
