League Opponent Selection System - Determined to be a Bad Idea

[calmon]

If something like this got implemented this may lead to a serious problem besides the cheating reason:

It could go to a point where invite only games will be the common way of starting league games and newer players/players without much contact via friendlist have serious problems finding opponents in the queue.
The matchmaking queue itself would be less frequently used in general which leads to longer waiting times.
