Hello. I have played League of Legends (LoL) for about 4 years and the highest rank I have reached is Silver IV. I will attempt to explain my opinion about the game and break it down best I can.
My first gripe is that champions and roles are not balanced. As of writing today, Yone is so overpowered that you are better off leaving the lobby than playing the game. There are other examples but overpowered champions switch as often as changing jackets.
My second gripe is that female champions are overly sexualized. Cleavage and even thighs are slightly visible (and also visible enough for the imagination) in most female champion art. Evelynn is heavily oversexualized that hormones are bound to go crazy. That's not a good sign.
My third gripe is with Riot Games. There are news articles on the internet that have accusations of sexism against Riot Games. It appears this has been swept under the rug for the most part but I recommend everyone to have knowledge of this subject.
Even after all this, I still like the idea of the game. However, dedicating 30+ min of time towards each game wears away at you. Even reaching level 30 for ranked will take you weeks depending on how many matches played.
You have heard my opinion and I now encourage you to make your own opinion on the game. Thank you for your time.
