I just have opinions as to why personally…
More and more people are playing DPS vs main tank. A lot of people just get tired of main tank, and the less people that take turns on it, wears out the good main tanks who just want to play something different.
A lot of the DPS playing do not know how to DPS. I can see this when versing an enemy team. I will have multiple games where I can steam roll the enemy dps, then out of nowhere, the next game, the DPS is amazingly on point.
I think ez win characters that ranked people up, and are no being nerfed, is causing certain people to be deranked, and swapping characters. They think they are a specific SR, but they are not.
New seasons, new characters, new maps, etc… bring back people who haven’t played in a long time.
6v6 team comps are insanely more difficult than solo. It seriously feels like a 500 - 1K SR difference.
I have had bigger swings in SR this season personally, but a lot for me has to do with the fact I am constantly having to play main tank instead of my main characters. And when I play my main, the main tank really doesn’t understand positioning because that person also never plays main tank.
Then on the flip side, vids being reviewed, OWL, and howtos are educating the community, so play styles and teams are just vastly better than last season. Add to that there are most likely less people playing this game, meaning less people in higher ranks, you really feel the pain.
