Play to Win... to an extent

I'm going to start off by saying sure, a win is a win, and I won't be able to argue against the tournaments rules, but there are certain limits to which I find this being abused. Wins generally are from one person taking all of the opponent's stocks, but they can also be from timing out the opponent. I think that this method should actually result in some sort of punishment instead of reward for being able to evade your opponent so long. This is a game that we play, and no one wants to watch someone float around the stage avoiding conflict for 6 minutes. It just isn't fun. It's also very unfair. Certain characters are actually able to completely avoid the opponent for extremely long amounts of time. Imagine a Wario, Mewtwo, or Villager, who is able to just entirely avoid coming into contact with a Little Mac. By camping you take away the fun of the game and don't even prove any skill. It is not skillful to win by timing out opponents in most cases. Because of how safe some options are like rolling, people can just waste 6 minutes of other peoples time. This rant was partially brought about by Dabuz, who plays only to win. I saw him play Wario, and completely avoid contatct for about two to three minutes, until his Waft was charged, then go into the fight with an unfair advantage. Then after he got the stock, he just waited around until he won. Sure, he did win, but did he earn it? I argue no. This is just a severe level of trolling, and I don't think our tournaments should reward it. IN tournaments, there should be some limit to time, but not reward someone for taking their opponent to that time limit. They should just both receive a loss if they can't find a winner in the time, or be forced to do sudden death. If we completely remove the time limit, tournaments could run extremely long, and I think that itself calls for a reason to have some time limit with more fair end of game procedures. These are just my thoughts, because I come from another competitive  game, that has completely terrible end of time limit procedures for events other than nationals. What do you think would be fair?
