As stupid as you guys may think this sounds. As weird and "blasphemous" as it may come out...
There needs to be a rule for DLC character inclusion in tournaments. There are many reasons, many I will list down below, as to why there needs to be a DLC Character Inclusion Rule in tournaments.
Now think of it this way, why should there be such a rule in effect in tournaments? Let me just say that I'm not against Smash DLC, but picture it this way. If someone is extremely good in Smash Bros. for Wii U, prodigy level even, and has never once paid for a DLC character or stage and then suddenly goes to a tournament with DLC characters allowed, since he or she doesn't even know how to go against the DLC characters, that would be ruled as unfair because the person has never had time to know what these characters do or how good they can really be. This is a very unfair thing to people who are in that scenario and you can't say it doesn't happen. You don't know.
This person who is really great with one of the starter characters who doesn't know anything about other characters (and has no knowledge of Smash Ladder either) would think this would be unfair since they never have went against them. They probably haven't bought the DLC since DLC is actually fairly high priced, they probably didn't want the DLC characters and just wanted to stick with the game normally or they just refuse to buy any DLC from any game. Those are reasons as to why they don't know how to go against them.
And in all honesty, it's unfair. Why should someone actually be able to pick a character that the other person has completely no idea how to fight against, when the other person will most likely lose for that very reason? The other person doesn't know the character's moves, they don't know how that other character works, and even in a tournament setting, there's not enough matches to formulate a simple comeback with the other person's own character.
Furthermore, why should tournaments be required to have all the DLC? That is actually almost as much of a hassle as Customs, only with the added consequence of having to pay for it. Tournaments should have the choice whether or not to actually have DLC characters usable or not. It's hilarious to even think that people should automatically need Ryu or Lucas or Roy or Cloud or Mewtwo to play a tournament when it's just not fair to the person who doesn't own them.
If there was a rule dictating that tournament owners have the decision to include or exclude DLC characters, then there would be no such scenario popping up with a problem. Consequences? Well, there'd be two sets of tier lists as a result (non-DLC and DLC), removing the unnecessary character Ryu from one of them to give better MUs, there will be no complaints from people who don't own the DLC and yet there will be people who complain about it when they do have the DLC character and play as them.
However, there is a remedy for this.
"However, should both people agree that DLC characters can be played, then DLC characters will be allowed."
It is like Dave's Stupid Rule, Gentleman. If both parties agree to the DLC character usage, then it can absolutely be legal.
If you really think about the big picture, there are going to be a lot of people without certain DLC characters or without all of them, and would it not be unfair if the person goes against someone who uses one of the DLC characters? Sure, there will be repercussions like another tier list (which would be good to have as we get another perspective on things) and having a different MU spread, but at least there won't be complaints that "someone used a character I don't know how to play against, because I never fought against them".
That little quote I just said?
That can be used as a legitimate John in tournaments. And the thing is, people can actually get away with it.
People can get away with saying they've had no knowledge of going against DLC characters whatsoever and call the match unfair if a DLC character was used. People can get away with that and it can be a commonplace thing too with some people under the radar who suddenly pop up in tournaments.
So either way you think about it, a rule like this would need to be necessary.
Or else you'll get complaints or Johns that people can get away with, saying that it was "unfair". You can't tell them [the legitimate people] to "get good (git gud)", because where are they to get good when they know nothing about a DLC character at all?
Any arguments for or against this?
