ARE YOU F***** KIDDING ME RIOT 30LP?

Besides the fact im so pissed off right now I just lost a game I should of won. I just lost my promo, I wouldn't be so much more upset if I didn't see I dropped down TO FU***** 62 LP? REALLY RIOT RELALY? IS THIS THE MARVELOUS RANK SYSTME YOU CAME UP WITH? Me spending hours trying to carry these scrubs over and over, and then reach promo and lose over 30 lp? REALLY RIOT REALLY? That is some complete bs of a rank system, FIX THIS NOW. I know im not the only one fed up with the rank system, like come on I spend hours trying to get promo, going through frustrating games over and not to mention the dominating when I was having until my team screwed up screwing me over with promo, now I have to play freaking possibly another 5 games just so I can win 2 games, even though I probably will end up winning 3 alone reaching promo? That's the type of logic I really hate with this rank system. Just complete bs. ruined my new years night with this crap.
