then again, i was sucked down the gsp ladder early by this horrible matchmaking system early on in the game's development. i currently stand at around 800k unable to find any competitive matches through all the casual bulls***. if there's no fix in 3.0 then i honestly think there is absolutely zero hope for the future of ultimate's online. it's that bad.
Oh, I wouldn't worry about GSP. It's a terrible system and sucks the fun out of the online mode....well, what little fun there is to be had there...
I have a friend who is particularly 'precious' about his GSP rating and I see what it does to him. It pushes him to play in an ultra-safe, ultra-conservative style, sticking to a very limited number of tried and tested combos. If he loses to an objectively better player, he won't rematch to try and learn from them and improve. He'll just bemoan the loss of his GSP, and will (probably) then go on to block whoever he lost to.
And that's what the GSP system drives people to do. It just puts you in a rut and it makes you highly-strung about every game you play. You just won't evolve as a player that way. I'm not sure you'd have much fun playing either.
I think that, if you can get into Elite Smash and stay there over a long period of time, you can rightly consider yourself a strong player. But outside of that, I think GSP means very little. Personally, I see no noticeable difference in the general quality of opponents in the 100,000 to Elite Smash threshold range.
My own GSP fluctuates wildly between 400,000 and 4,000,000. But I'm still the same player. Where it sits in that range entirely depends on the luck of the draw in the matches I get. If I get matches aligned with my preferences (I'm happy with time or stock matches, items off, either on Omega or Battlefield) then my GSP rockets upwards. If I find myself on free-for-all, max items on ghastly scrolling levels like Pacland, or 3 stock 300HP stamina matches, then part of me dies inside and my heart won't be in it. So my GSP plummets again.
And then, of course, you get matches you lose because the game lags at a key moment (like during recovery), or you have an unlucky period where, if you lose, you lose GSP, but, if you win, you gain no GSP because your opponent has rage-quit half way through.
It's best just to ignore it all. It means nothing. It's just another in a long list of awful design decisions Nintendo made for this game.
