LP in ranked needs to be relooked at

So ive been playing a lot of ranked lately and its completely mental how the LP system works. I get that you should have to win more games than you lose to move up, but you shouldnt get put down for little losses either. I was at 50 LP won 4 matches in a row and only got up to 98 LP. after a FOUR GAMES WIN STREAK. Then after i had 1 loss i was dropped down by 25 LP for a grand total of 73 LP. I understand that if you lose it should hurt, but this is just unfair. This means even after winning 4 games in a row i received less than 50 LP which means i get less than 13 LP per match. This means even if you win 50% of your matches you will be moved down in rank. Being moved down even though you have a 50/50 shot to win is just not right. It should a little more balanced then that. Im sure its not just me that feels this pain. I feel there is a balance issue in ranked and this should be looked at.
