Im completely unsatisfied with the new ranked reward system. Can somebody give me a reason why this system would be better than the old one?

Last season I climbed to Champion. This season I got placed Platinum and was in no time Diamond and right now, after about 15 wins (silver 3/12...) I'm in high Diamond and Champion feels reachable. But I just hate the fact that I need to win 12 games per tier to get the rewards.

It just feels not rewarding for me at all. Divisions and tiers don't matter right now, because I'm still fighting over my silver reward wins with other Champions. I'm in Diamond, and if I win a game against other Diamonds/Champs I just get one win for my silver rewards. cool, thanks.

I guess I'm not the only one who absolutely can't stand the new system. But I'd like to hear reasons why it's better than the old one, so I can maybe change my mind. I guess one of the reasons was to have less players that got Champion for example but never would have sustained playing at that level.
