When You're in Promos...
...you should be able to go above 100 LP while in the series. This is a very small thing, but if you win the first game in your series (of a best of 3) you currently get no benefit, as you're already at 100 LP. If you then proceed to lose the next two games, you are a bit cheated. To explain: if you lose the first game, then win the second, then lose again, you're better off because you dipped below 100 LP for the loss and thus can benefit from winning one of your games. Why does one of the two ways to lose a series have a much better outcome for the player? So, simply, while in a series you should be able to climb above 100 LP in order to make both outcomes equal for the player. Losing a series sucks, but is inevitable as a player tries to climb. They shouldn't get shortchanged by the order of their wins and losses in addition to the sting of losing a series.
