So the whole ranking system..

So I am a decent player. In my opinion i am an Onyx player hands down. I never played Halo 5 competitively until i joined a joke of a spartan company until i decided to go out and make my own about a month ago. I somehow have only made diamond 4 in slayer. I have a decent KD and i am pretty damn good at slaying. This season i won the majority of the qualifying games and went positive in almost all the games and made plat 5 lmao. Some of my buddies were champions and were extremely pissed when they ranked in diamond for the March season. Did 343 make it harder to get onyx?? How long do i have to grind to get Onyx? Any feedback is appreciated. Thanks guys

yes they made it harder because players were getting better. it is what it is.
