This season being bad and unfun is not a coincidence
Season 6 was horrible and yet the exact same people who worked on it now made season 7. What did you expect?
That suddenly the balance team would become 10x better without any adjustments to staff, that Ghostcrawler would see the light and become a competent head dev, that Repertoir suddenly would get the touch and make good reworks after failing on all of them, that Meddler would stop his bias to randomly buff/nerf champs and force them in and out of meta for no reason. And it is not just them. A lot of Rioters behind the scene work with them on these projects. What about all those people who worked on class updates and item updates which turned out to be a disaster. I am looking at the Mage/Assasin/Tank/Juggernaut update and their corresponding items which are now all a complete mess.
It is not the game that is bad. The core of the game is good, its the current staff that is bad and think they are better devs than the ones who created this game in the first place. They think they can outsmart every important lesson learned in the past and everything needs to be 'improved'. I am not looking forward to season 8 because of runes changes, I am not looking forward to season 8 because the same retards who ruined season 6 and 7 are now working on season 8 so my expectations are zero.
You can not work on the game when the staff is broken at a fundamental level. Fix your staff please, then work on the game.
