Wouldn't it make more sense if you just earned/lost a flat amount with every game? Maybe I just don't understand how the LP system works, but the amount that you gain/lose feels extremely random a lot of the time. Personally I wish it was just a flat amount that never changed.
RiotMeddler8 votesIt's based off how your MMR compares to the average MMR of the enemy team. Their MMR should be fairly close if you've been matched together in the first place, there's still some variation though. For a game where your MMR is lower than their average you'll gain more LP (it's a game you were statistically less likely to win, so the reward's higher). For a game where your MMR is higher than their average you'll get less LP.

Thank you for explaining this. I'm still slightly confused on how MMR works, but this does explain why the LP gains/losses vary so much with each game.
RiotMeddler2 votesThe general approach is fairly similar to the Elo system. Wikipedia's got a pretty decent write up on that:
https://en.wikipedia.org/wiki/Elo_rating_system
I gather the LoL MMR calcs do have some other stuff going on as well, particularly around things like placement matches, adjustments for queueing with others of significantly different MMRs etc. Not certain on the details though sorry (not a side of things I'm too familiar with).
AramsAreBest1 votesAre you ever going to rework the placement and 5 player elo idea?
Aptest1 votesI will give a different explanation:
LP gains are a non-functional display layer that works off MMR with both high gain and high lag. The LP gains are designed to roller-coaster wildly around your actual MMR to fabricate a false sense of loss / achievement and also to kill the ability of a player to have good high quality insight as to his own skill measurement.
TL:DR: it is designed to appear random because that messes with your head.

This guy gets it.
Orinne3 votesYou win more and lose less LP if your MMR is above the rank you're currently at. You win less and lose more LP if your MMR is below the rank you're currently at.
There's some variation in this based on the MMR of your team and the enemy's team (eg. if your team has more MMR than the enemy team, you would lose more LP if you lose).
