Honest response why game feels unfun right now
For me the game hasn't been very fun this season. While there are a lot of reasons I could get into including lethality and people not adapting well to the new runes there is one big reason that holds true every game.
You never feel strong anymore, the whole game is putting out fires constantly. Whether that's having to watch objectives that fall in a few seconds, or trying to stop the enemy ADC from getting fed, or stopping your allies from being caught. You end games just feeling like, "phew, no one did anything stupid that time."
I want to get to a point in the game that I feel strong instead of constantly struggling to keep everything else from getting out of control. That's the single biggest problem right now.
