Ranked System and LP
Preamble: After giving ranked a somewhat more serious go this season, I finally reached gold, however I have some major issues with this LP system. It took my 70-ish games to reach gold from unranked, so I know my ELO score is still probably fluctuating with a higher variance, but I think the whole LP system is bad, especially when it comes to promotions.
Issues: The promotions require you to have a 2/3 win streak, or 3/5 for tier jump. That's a 66% win rate or 60% win rate, however the whole point of MMR is go place you at around a 50% win rate, and if you're doing well, you'll be up around 51-55%, very well 55-60%. On top of that, the system matches you with people who are your ELO, so I've been playing vs golds as a silver player ever since I skipped to silver 2 from silver 4. When I'm matched against a team of silvers, the game seems to go very easily. Thus, if someone is in a certain ELO, that should be their division. None of this promotion nonsense. Just like starcraft 2 does (did.. haven't played in a while).
A completely other issue is this... people in their gold promotions suffer from serious trolling or complete apathy (which is more likely). Often a sour teammate will on purpose sabotage the game. And even if they don't, I noticed most golds who are already set in their ways don't try at all or care that you are in your promos, and will surrender etc since it's meaningless to them. As a silver player trying to promote, you should be matched with other silvers near promotion, or golds fighting off demotion. Again, the whole stress of promotion could be avoided with a better system using a more transparent system (0-1200 ELO bronze, 1200-1400 silver, etc etc). I guess they are trying to avoid people bouncing between boundary points, which can be resolved by creating many sub divisions, and only change it when the standard deviation is fully underneath or fully above the threshold. Just some thoughts.
I know this is meaningless to most people in even higher elo, but for lower elo people fighting to promote to gold it would make the ranked system a lot more enjoyable.
