The Real reason why League of Legends is becoming no longer fun to play
im gonna get a sht ton of downvotes for this :D
Let's have a little flashback to the past
When you just started playing LoL you pretty much expected nothing so when you got to kill your opponent you get your share of dopamine and it's dopamine so you want more so you play more so you kill and win more so you enjoy more
now, you expect kills, wins, killing sprees, stuff, etc... when you lose/get killed constantly you get less than what you expected so you feel miserable and start feeling that the game is unfair / no longer good and usually you would blame it on the recent changes or the general changes in meta
and also because Jax is broken asf
please note that this doesn't have to be the case to everyone it's just the common case and also this is a quick explanation of everything and you probably get the idea
the solution? get a life
or find another game that you like
you losing your interest in a game doesn't mean the game is dying
