@Riot, why do you punish players for Loss Streaks but not reward them for Win Streaks in Ranked?
Losses that would put you at less than 0 LP (i.e. losing @ ≤10LP) count towards your Demotion Series. This means you can be demoted after only 1 Loss at 0 LP.
Wins that would put you at more then 100 LP (i.e. Winning @ ≥90LP) don't count toward your Promotion Series. This means that you have to play a minimum of 2 more games to be promoted after reaching your Promo series. Even if you were sitting on 99 LP.
Where's the consistency?
