Don't you think that losing streaks punish you a bit too much ?

Got placed in silver 1. Climbed to 80LP gold 5 without many losses (2-3 i'd say loll). Had plat 4 mmr, basically i were the only gold player in my games. Lost 4 games in a row, my MMR is gold 3 and i wont get 30+ LP a win. Dont you think it's a bit too much ? Proofs:

• Yes, i clearly started with W/L every game there, but my mmr was still plat 4, i was checking after every won & lost game

My beatuful winstreak, farewell http://imgur.com/a/VvwK7

Will i lose like this until they screw my mmr , and force my winrate at 50% ? So i'll lose another 10 in a row to lose my 70% WR.. lul.
