"Ranked"
Is not at all ranked. It has absolutely 0 to do with skill and all to do with luck/champion. One team gets feeders one team doesn't get feeders, that's it. That's what your game is. One team feeds one team doesn't.
Please Riot learn to make a real game that requires skill.
Bring in the downvotes but I speak the truth. Argue my point. I dare you.
Have a "skill based" game that requires no skill but all luck makes no sense.
