Just like DOTA, LOL has 3 lanes the top lane,middle lane, and bottom lane and their is also a farm or a jungle. The top lane is where the tank champions are fighting or some player use attack damage (AD) champions. The top laners in tournament uses tank champion because their the one who will started a clash. Tank has a highest armor and a magic resist for ability power (AP) champion and they have a highest heath. They also hard to kill because of the items they use in the game. The middle lane is the center the map and it is where the ability power (AP) champions used. The center of the map is usually having a clash because some teams always attacking the mid laner of opposite team. The mid laner is the common carrying the game because of its ability power (AP). Ability power (AP) is used by the champions that always uses skills that a melee fighting. In bottom lane is the attack damage carry (ADC) in here in the Philippines we call it attack damage range (ADR) because this champions is range type and there the one is hitting from the back. ADR or ADC has a low health and easy to kill. There support is always protecting the ADR and it help the adr to get a kill so that it is easy to buy a item.
The most famous LOL player is Faker of SKT T1. Faker is a professional mid laner and he is famous in using zed, leblanc, yasuo, orianna, and ahri. He is the one of the highest paid player in LOL because some of the companies in South Korea paid him for playing LOL. For me SKT T1 is the best team in LEAGUE OF LEGENDS tournaments because if there styles in playing and they have a awesome team play to win the tournament. The SKT T1 has a 6 members Marin (top laner), Bengi and Tom (Jungle), Easyhoon and Faker (mid laner), Bang (ADC). Wolf(support). They are all in challenger division it is the highest division in LOL.
