@Riot Why not do away with promo series?
I started playing in s6 so I don't know how the ranked system was before how it is now but I feel like ranking up when your mmr reaches a certain point would satisfy a lot of players. I'm sure most can agree that going through promos is a negative experience because it feels like match making is working against you.
You guys know a lot more than me so could you guys enlighten me to why this system isnt in place?
