Is it too late to complain about the new ranked system?

Seriously Riot, please bring back the old elo based system. There is nothing more frustrating than getting into queue getting the desired role, getting really excited about that role, and then not being able to play it because someone dodges, and then I have to play a role I am less than excited about playing because of this so called 'random' system (thanks to dodgers I have been the last pick in about 4/5 of my last games).

At least with the old system I would typically be moved up or down only one spot. People in the bottom pick DESERVED to be in the bottom pick. There were times I was bottom pick and guess what, I sucked it up and filled, because I was there to be carried. I knew it, my team knew it, hell the enemy team knew it. With this garbage I have to play support to a carry that doesn't realize as Jinx its probably best if they switch to their rocket when they are below 50 health and getting healthy harassed in the early levels.

I don't post very often, but this is something I do feel strongly about that is ruining my, and I would feel others would agree, their experience. If people really like random pick order, why don't they simply play draft pick normals?
