Is it just me, or could the league system be way less complex with no effort at all?
Step 1) no MMR. You're matched based on your league and division
Step 2) you can drop from Div 5s, but no promo series. You hit a hundred LP, you go up a division. Simple.
Step 3) base LP gains and losses on matchup favor ability and a limited streak clamping.
No more confused players gaining 10 and losing 30, no more playing Gold 1s to get into Gold V, no more Elo boosted baddies ruining games and still getting Gold V rewards.
I don't understand what the drawback is...
