Now people start to realize that how absurd the current elo weight for mm matching is. This is the reason why we have 45 min q when there is 5 available and can't even launch a single 2v2.
There is nothing wrong with teaming up. RTS is about strategy. It means trust. Trust and predict what your enemy will do, what your ally will do. There is just nothing more comforting than getting "sending penns omw" from your ally when your spider is under firewalker. Fighting with a stranger you have not ever heard or met is not making the game more "strategic".
Teaming up is getting suppressed; the elo matching range will even become shorter according to this post(http://zero-k.info/Forum/Thread/25687), and that's evil. The original author of this post doesn't even frequently play mm anymore and the inability of seeking someone you can trust with and predicting the game got officially encouraged without even a vote at the expenses of other people's (those who are coming prepared and who are working hard to strategically play.) time.
That opens the new point: Why can a single dev with a gigantic permission change a setting without a vote in an opensource community? Dev is having too much rights and abusing rights brings no good to the community. This is what currently happening in other opensource communities too, because core developers are abusing their rights, we have OpenBSD, we have dragonflyBSD and freeBSD, we have warzone2100 and we have linux distribution vs android. Vote is good, and please keep voting even on the very basic dev level. It shows what majority thinks.
Therefore, in conclusion, I do not think teaming up is bad, and its elo matching range shouldn't be deducted.Vote may not be able to solve everything, and for the balancing issue it may also suggest the opposite as this post suggested, however, I believe a vote gives a better result than someone asking someone else who in charge of summer pw and all of the sudden setting changed after all.
