You do not know anything about tournaments (you've never been to one). You do not know how tournament Smash and tournament videogaming works (you've never been to one and I doubt you've read up on the subject). You do not know how Final Smashes work (because then you'd know some of them are just too good and would over-centralize the game). You do not even know in what way they favor the loser in such a way that it is unacceptable.
This means that you do not possess the necessary knowledge to form an informed opinion and coherent argument. Before debating something, I suggest you educate yourself in the matter. And also, do not try to change the ways of a group you are not a member of and will most probably never become a member of.
Why were Smash Balls banned in Competitive gaming? We had our reasons. You clearly do not know these reasons and just assumed a hell of a let about them. You then assumed you knew everything there is to know about Smash Balls and that we were wrong in banning them (or at least banning them and not D3's infinites).
When I then told you why you were wrong, the information I fed you was so above you you didn't understand it, even though you would if you had really studied the game and/or Smash Balls.
And you are still arguing as if you are correct. No, you are not. The logic employed to ban Smash Balls cannot be employed to ban D3's infinite!
