I haven't played LoL myself, but I've heard that it takes ages to buy the champions with ingame currency. To me, it is also a pay to win concept if it just takes way too long to buy things with ingame currency instead of cash. Or, in free to play shooters, if you're required to play at least 4 to 6 hours a day in order to have enough ingame currency for your equipment.
