There is no doubt that the latest area has the most pits. Now the old areas of LOL are basically closed. The older the area, the longer it takes to play. The fewer newcomers there are. In fact, if electricity 4 and electricity 6 are used. The level should be similar, even the electricity 4 is better than the electricity 6. As for your classmate, there are many pits in all districts. But if the record is poor, then you have to find the reason yourself. It is also possible that he did it himself, but most people in Cheating don't think they are pits, but they think their teammates are pits. That's why everyone tells others to cheat.
