Why Riot

Ok Riot, this is the one and only complaint that have about your ranked system. I just lost my promos and after the loss I was place with 62 LP... This means that in order for me to get back I need to play a MINIMUM of 2 games. That makes 0 since to me. Typically if you lose your promos (especially 1w 2L) you would only need to win 1 game to get back to promos, but as it is now I'm required to win the next 2 (possibly 3) games just to get back in. WHY?!?!?
