You're playing smash for money then you're m2k. Otherwise you're just trying to piss everyone off.I'd say you're being the downer; saying someone is weak because of a smart economic move isn't exactly positive.
This is a competition, a competitive game, not a money-making scheme. If I looked at it that way, I think I'd more more saddened by Pound 5, but I'm not. Why? BECAUSE I WON. Proving myself is 400X better to me than a few thousand dollars(even if I could've used it well).
And I'm not trying to put someone down for being competitively weak. It's their decision. I will keep having an opinion on the matter and will give it if I feel the need to though. I have no idea why you'd take the decision personally when this wasn't even directed at you.
Edit: Thinking about it more, if you won once, then wouldn't you want to do it again to get more money? Seems like you could even be selling yourself short so to speak if you just let the opportunity get away like that.
