Losing is a part of the deal. Only a few people never lose. I will agree that GSP matchmaking ends up pitting players in a sliding scale. Happens to me all the time. First battle is always tougher and you have to lose several matches in a row until your GSP sinks to the next skill bracket. Then of course the match is too easy lol. And if they or you rematch and you win a bunch your GSP soars back to or maybe a little higher. But as soon as you break with that easier group your NEXT match will undoubtedly be just as hard if not harder than the original start.
Another thing to "blame" is ssbu new game mechanics. It was a harder adjustment for me going from 4 to this than it was to go from Brawl to 4. I eventually reached my usual skill level but it took twice as long. But as with the previous games I was able to get in before the vast majority of other players had reached the same level. But going on 6 months after release I'd say 3 mil gsp or higher will be a good cutoff for expecting a challenge in your case.
I am willing to bet if these matches were not visibly ranked losing streaks would not play as hard a mind game on folks as it apparently does.
