Dick Rider syndrome, lots of people will try to get acknowledged by someone famous when they are in a game with them, aside from that, generally the better you get at the game the more inclined you are to realise how your mistakes impact the game, making you rage less, at other people. I tend to only get upset when someone makes an absolutely idiotic mistake that only someone sub 100 games should make.
Didn't know you played DOTA, how's the burgh.
It's honestly hit or miss, sometimes it'll match you against people at your level, and other times it'll just find 5 solo players or 3/2, 4/1 configurations to get your game going, and it seems to be completely random as to when it'll stop looking for a group of 5 in favor of a quicker match. Sometimes it'll take someone good and just throw them together with medium skilled players. It's hard to see consistency with the system unless it's early afternoon / late at night when the pool of players is smaller, or when you do modes such as CM where the pool is much lower then AP.
