The real issue about placements
Alright, so I notice everybody gets screwed over in their placements and I don't think it's the actual system that's broken but just how league advertises it as a way for you to potentially get a "large elo swing". This is misleading, because what they really mean is you're going to drop a ton. It's the reality. I don't believe that the placements are intended to be a place to increase your rank even though that's what they suggest. The intention of placements? A positive and fun way to make you feel better about the fact your elo is going to be dropped. The purpose of this is so that everyone's elo becomes closer together, and because of that you're going to have to work up the ladder all over again. It's up to you to make the most of it.
