It is just frustrating to fall back after I finially reached my purpose (1300 points in rapid).
Does games become harder after I pay premium membership?
I have started to use premium and my rating dropped 100+ points right after it but I do not think I played much worse than usually.
you're probably just getting unlucky with the matchups
When i purchased platinum membership i lose alot. unlike before i purchased the platinum membership but its ok since i get more experience and i can get better.

Everything is easier once you get premium. Your opponents are idiots and you win every game. They deliver mocha lattes to your door. Everybody on the forums admire and respect you. The moderators cut you some slack. The server never fails you. Premium membership is just great.

It could be because you are learning taking in new information. Brain needs time to rewire. Just calm down.

same I have reached 1800 rapid then i purchased premium but then I started losing a lot more it's almost 2 months i can't reach peak but instead losing more than 50 points
The answer to this is yes. I don't know why everyone is being a [removed -- MS] about this. It's obviously harder with a paid account.
on premium i was 1400 for 3 years
on the free version i'm 1700 and holding for already a month.
so dont tell me this is a coincidence
