Should I really lose my promos to this team?

Me and my adc played really well and won our lane. But the rest of my team (even with me roaming a lot of the time) just fed their lanes... So I just lost my promos to a team like this and also down 60LP. I think this is really unfair as I've still got a 75% win rate but getting teams like this in promos is honestly making it impossible for me to rank up. I personally think at least you should give players a higher LP if they lose their promos because now I have to play at least another 4 games to rank back up.
