"League of legends is fun to play"

I used to have so much fun playing this game with friends and playing solo q, now league is so bad ive gotten to the point I no longer have fun playing this game, The players who play this game rage, trash talk, and leave games constantly the second one problem occurs in the game. This usually wouldnt bother me but 80% of players in my game react this way becacuse the game is such in a bad state that, one they arent playing league to enjoy it or win they are just queining up, and two becuase the amount of champs you can play in each role is about 3-5. If you dont play those OP champs because their kits are overloaded with dmg and runes make it 10x worse than you will lose the game. One example of this is lissandra mid, there isnt a strong enough pick to 1v1 in her lane or trade evenly with her. All the mages are terrible unless you play zoe and even then zoe gets outscaled if she goes even or doesnt get ahead if the enemy team has tanks. Lissandra damage increases throughout the game and her kit makes her useful at all stages of the game. It gets so tilting for players to be forced to play theses picks that they dont want to play in the first place, or even that the champs they want to play, players arent able to because the 3-5 champs that are actually viable in each role destroy all others.

In summary this game is no longer fun at all to play at all, I dont understand the point of riot making new champions when you can only win playing 3-5 in each role.
