Why am I level 5 but I always get paired with level 20s+ and sometimes even 30s...? I am new I play on NA from Vietnam but I have this question, is it related to the people around me?

I tell them "I am level 5" but they laugh and don't believe me until end game. I don't think matters but I use Master Yi :-D

There just aren't enough people in queue when you are playing. If you queue in the middle of the day in Vietnam its the early morning here, no one is on. So for you to even get a game they gotta put you with anyone they can get.
