Getting old with the GP disparity - every level is having this problem besides Kyber 1

I guess my question would be why not let a person only drop one class then the highest they have achieved. Everyone should want to go higher. For better daily rewards. This would stop the sandbagging to at least one class. I say one because sometimes you can win by good strategy or match ups as well as lose. The championship should be encouraging one to climb for the rewards. Whether daily or during tournament. Some just figured out how to maximize that by playing lower rosters. It discourages participation. I love when I win, as anyone would,but it sucks to lose to someone you know you shouldn't be matched against.in fact in my round right now I am at 556 arena rank the last place person? 31, 4 of them are in the top 200. 2 are less than 400. The leader 418. How did I get matched to this? I get it Arena rankings can be misleading. But I struggle to climb arena. These people clearly have good rosters and the certainly don't belong in chromium 3. I just fell to chromium 4 because of this. And I know I probably didn't belong there but elevated because a few i won was because they simply didn't battle. I am not notched to the strongest roster and if I win it's because he wants to drop again. If I win it's because he didn't try. If I lose, it's only because he wants to maintain his tier.
