Its because of those people who take hours to connect to anyone. I've been connected to two of the three players in the game, and after five to ten minutes the third person still hasn't connected at all.
Though usually when I kick someone I crash to the desktop, so I end up just leaving the connection attempt and find something else.
I would agree with this if kicking then found another player to replace the kicked player, but this is not the case. Right now kicking a player removed the player from the game and is not even replaced by an AI (which arguably would be worse). Personally if the game doesn't replace a kicked player with a new player the game should at least remove everyone from the game so we do not have these imbalanced 2v1 or even 2v0 games.
