Since leaving games doesn’t affect winrate, it’s possible for people to bottom out their mmr and have a high winrate. If a person only plays ‘1 or 2 games’ in a week and they disconnect once a month, than 12.5% - 25% of their games are incomplete matches; they wouldn’t play enough to offset the leaver penalty and their rank will plummet.
People are saying your anecdotes have incomplete or incongruent information. Considering how people have been trying to give you advise for years, the accusation that something ‘doesnt exist’ is more likely to be on your end. These are players that climbed out of bottom ranks and aren’t there anymore. You, on the other hand, come back time and again to report that your rank is lower than the last time your reported your storm league experiences.
While ‘trolls’ are something usually out of our own control, other aspects of the game are more-or-less things we can influence, but time and again you pretty much deny any experience or advise as being unable to work for you. Despite claiming to not care about certain things, you continue to do them, so either you mire yourself about in apathy, or you aren’t completely honest about particulars that, frankly, don’t really matter to anyone else but you.
However, the usual trend here is that people try to help others because they find the experience is better when people aren’t playing on the low rung. While people may have increasing amounts of vitriol in communicating with you for years on end, it seems the ‘religiously defend’ is something better suited to describe your resilience to learning and improving.
iirc, some posters even used to watch some of your replays to offer direct advise. Granted, the best strategies can’t overcome perpetual leaving or disconnects, but it’s a farcry that people keep trying different ways to assist you (outside of group/carry) and time and again you are the one that blows in back in their face.
Fundamentally, people that just look to blame any and everything else simply don’t improve; if you’re content with that, then people can’t help. Pretty sure I even had a ‘luck is a skill’ reply made at you regarding your concerns of bad luck, but at the end of the day, you are the only one that can change you, especially when it comes down to half-hearted communications that pretty much look like you’re going to argue with yourself if they go on long enough.
