Not just directed at you, but everyone complaining about the new league system and their bad games, we have a nice, fancy rage thread over here: http://www.mmo-champion.com/threads/...To-Vent-Thread!
Please use it. You will get no sympathy if you post here.
I haven't had any weird LP bugs yet. I lose as much as I gain, which might be a bug but since the Elo system was the same way I doubt it.
