GSP Sucks

I'm so tired of GSP in Super Smash Bros Ultimate being complete garbage. You have to play 1v1 with no items to gain any GSP, or else everyone just leaves. Most of the times that I win something that isn't a 1v1, the first person to lose all their stock leaves and you get no GSP. Yet I never leave, so I end up just losing GSP when I lose and not gaining any when I win. Gaining GSP isn't even about winning rounds, it's about winning a round that no one leaves. And it's completely stupid. Is it really that hard to say that if someone leaves a round of Super Smash Bros Ultimate after they run out of stock, that everyone still gets GSP? The GSP ranking system completely sucks and I'm really tired of winning rounds and not getting anything for it yet when I lose I lose GSP. I might sound like a salty loser but this is just stupid, you should get GSP when you win the round, it doesn't matter if someone leaves or not, especially if they are out of stock and can't even play in the round. I don't know what's been going on, but leavers have been excessive, making up the majority of my matches on my characters between 6 million and 8.5 million GSP.

I don't know how they have not fixed such a stupid system where you don't gain GSP if someone leaves after they lose all their stock. The game is almost three years old yet they haven't realized this is a problem and they don't care. At least if you are going to make such a stupid system, don't have some sort of elite reward for being in the top percent.
