Promo Helper actually harms you
The idea behind promo helper is good. The execution is not.
In previous seasons (or when entering a series without promo helper), your lp total after the series is calculated based on your W-L. Go 1-2 in a 3 game series? You lose 1 games' worth of LP. Go 0-3 in a 5 game series? Lose 3 games' worth. If you enter a series with promo helper, however, the free win is not calculated into this, causing you to lose more games worth of LP. I just failed a 3 game series with promo helper, and lost 34 lp because the free win didn't counterbalance a loss as it had in the past. This is the second time this has happened.
