Why do I get +16-18 lp when I win but -21 when I lose?
Title.

Because your MMR is below what your rank is.
Win more than you lose and you will get more from a win than you lose from a loss.
because you lost a few games while at 0 LP or have a negative winrate
Because when you win, it's not because of you played well. But when you lose it's all your fault.
This is truly what Riot thinks. Especially with matchmaking intentionally putting you with people on loss streaks if you're on a winning streak.
Because matchmaking failed. Algorithm thinks you don't deserve your current ranking, but algorithms put you there. Shit design. Sorry for you.
