I assume you're not aware of all the caveats involving hidden MMR and its relationship to your LP gains/losses? The system just thinks that you're playing at a skill level far below where your Elo suggests and is adjusting your LP to reflect it.

I'm in Bronze 1 at the moment and I gain about 25 LP when I win and drop about fifteen LP when I lose, so the system pretty obviously thinks I'm below where I ought to be. I don't find that surprising seeing as my main duo queue partner is in Silver 2 and he claims he's seeing roughly equal gains and losses all around (meaning we're playing at a level that's about equivalent to his MMR).
