there should be a required league knowledge test for rank.
because some of the people that play this game are pure clowns. rushing full armor and zero HP as nasus vs a teemo and wondering why you lost lane and cant do anything after feeding him and continuing to not build MR. the fact that your lane wins because your own teammate is an idiot is the ONE thing i wish can be controlled. even in OW or HoTS if you have one or even two stupid teammates the rest of your team can still pull his weight. not this game tho.
