I have a big issue with how Riot see's Placements.
I spent the entirety of the last season earning my Rank. I don't need to be dropped an entire tier and have to re-earn my rank every fucking season. Riot's whole fundamental mindset is all wrong. There's a lot of players who simply want to go from Bronze to Silver in a season, and then Silver to Gold the next. They shouldn't be subjected to having to climb 2 whole tiers every season if they want to improve on their previous season's rank. It's absurd.
