I don't ward, the only time I've ever bought a control ward is when I'm trying to get an S rating on a character for mastery, I don't split push and don't play around objectives. I rarely can beat anyone in a 1v1 even if my character should win (everyone anywhere near my rank can vastly outplay me). Regardless of this my account is always between Silver III and Silver V (since the change that made golds place in silver when they added a rank). I personally don't care what my rank is and just play for fun. It doesn't really matter what I do, sometimes I play Kat Support, sometimes I just farm in jungle on a non-jungler and don't help my team, and aggressively try to M7 during ranked games with excessive CS farming on roles that have no business taking it. Regardless of my performance my rank is always Silver III to Silver V.
My account has swapped between 80-90% win rate to 80-90% lose rate each part of that cycle playing out over a 20-30 game course. I'm not the only player that experiences this. It doesn't matter how hard I try or how little, I'm going to win 80% of my games for about 20-30 games then I'm going to lose 80% of my games for about 20-30 games.
When it matches me with Bronze MMR on the deep end of the losing streak cycle they are incredibly challenging to win against until I begin my winning streak cycle in which I can almost 1v9 them.
- 80-90% win/lose cycle alternating every 20-30 games isn't natural.
- Bronze stomping me in skill vs being easy to win against depending on where I am at in the win/loss cycle also isn't natural.
- I've played hundreds of games so the pattern rules out luck I'd say fairly well.
What I've learned from this experience is that LoL can assemble a team of bronzes that are vastly harder and more skilled then any silver team quite reliably and it can also make bronze and silver teams which are vastly less skilled then those bronze teams. Also I'd say the long standing alternating win/loss streak patterns is enough to say that your skill and chance isn't the only thing at play here and that LoL has a lot of behind the scenes systems manipulating match making.
