The pros and cons of league if legends

I just wanted to start this discussion to discuss what people think the pros and cons of LoL are. Here are mine:

Pros: Fun to play Well developed game Stays fun and exciting after playing for a while

Cons: Sometimes too addictive Players that don't take it even a little bit seriously (most players are not like this) When you play a game and all champions are good counters against your team and you have a disadvantage because of this.
