Losing More LP than gaining, losing LP even with 65% Winrate!

IDK what the hell is going on but since the update I keep getting only +12LP for wins and -24LP for losses. Wtf is this, I lose LP even with 65% winrate, this is unbearable, I would need to win 2/3 or 66.6% of my games to not be losing LP, is Riot trying to make me quit this game?? The amoung of LP I gain or lose DOES NOT!!! correlate with my KDA or winstreak as someone suggested in my previous post, it does not change!
