The tier system and the division system are a good way of ranking players…
But in my opinion you shouldn’t be able to gain any rank probably above Gold/Plat after your first 10 Placement matches because its stupid that you play 10 games and are handing diamond/onyx/champion already.
Another problem is that while in your 10 Placement games, you shouldnt be matched up with and against players in diamond/onyx/champion… because whats the point?
Not being funny but in my 3rd Team Arena game i got put against the 3rd highest player in the gametype… Champion 3… let alone the other 3 players on his team being onyx… Its like the playlist has already determined my rank even though i havent completed my Placements yet… so therefore my games are even harder and the chances of me winning are even less… so then you end up with a worse 10 placements and end in a lower division so you have to climb uneccessary divisions of which you shouldnt even be playing in.
Halo 5 has pretty much adopted the same ranking system as League of Legends… as far as divisions and tiers go… but the rest within how it all works needs re working.
