Imagine you're playing against Teemo, and every time you try to attack him, he blinds you with his poison dart, causing your attacks to miss. On top of that, he's planted mushrooms all over the map, and if you step on one, it not only damages you but also slows you down and reveals your location. It's like trying to walk through a minefield.
I've been playing lol for 2 years, and until today I haven't been able to enjoy the game, but my colleagues with weak PCs play, and it's a good time to socialize, as each person goes to a different place in the country
