All that work to get demoted after one loss.

All of us trying to enjoy the competitive aspect of league would love to get those end of season rewards. We deal will all the bad players, the DC's the afk, the toxic teammates, the trolls and continue to try to carry our way out of bronze and silver so we get something for all that work. However i've been dealing with something altogether riots fault that makes me want to give up entirely. I climbed in the past month from bronze 5 to silver 1. however I cannot make it past that. WHY? Everytime I enter silver 1 i start with 0 lp, I win a game then lose a game, and then have the biggest troll of all time force a loss at 0lp and i get demoted to 75lp in silver 2, forced to get another 25lp and win a series. losing just 2 games in a row, requires me to repeat the entire process of a promotion again. There are some games you just cant carry, and losses are common. Heck a 50% win ratio in ranked is considered good, and you're going to demote me because of 1 troll and make me play another 30 games to get back to silver 1. I've repeated this close to 5x in the past month and can't get beyond silver 1, stop demoting me so easily! FIX THIS
