I'll just say a few things.
First off, I really don't like the attitude of people saying, "Will only got that far because of how he played." Will is a strong player and was able to abuse the living **** out of a strategy made available to him by the ruleset. Anyone was able to do it, but apparently he did it really ****ing well. And even if he hadn't, he's still a great player. Relax.
Second, RB has every right to be mad, so I don't feel like any apologizing is necessary. As much as it isn't Will's fault, if I was RB, I'd be really ****ing pissed. It's just the situation. RB is human, he's not gonna lose because of something that is both out of his control and just stupid, but then walk away and say, "Oh, well kudos to Will for rulesetting me".
Third, Will will most likely give his thoughts on the entire thing this week on Directional Influence, so check out the next episode this Tuesday.
Oh, and fourth, obviously every big Smash tournament will now have some sort of drama. It's a new trend.
