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

Well my last match up whoch is on going now,the person has 6.8 GP and 3 GLs. Being f2p is irrelevant yes and not my point. But being f2p one does rely on the rewards to advanc more so than paying players. I can say this, where I am, them dropping 2 levels, the rewards would have to be higher in the long run. Or as you said it makes no sense. If they are sitting at 5-7 they get 250 right now in a round. 500 in 2-4. If they can go up a level and can not progress past 5-7 it makes better sense to lay back and get 2-4 regularly and still make better rewards even with the daily being lower. Without posting ton on pictures. This one is patron now ranked 41 in arena. I agree it makes no sense.
I realize some will always look for a reason to sandbag for personal benefits. Whatever they may be.
This person however in no shape or form belongs in chromium 4.
It seems wins and losses are the major determining factor. And nothing to do with roster or GP at this point. Not from my match up.
