I just recently joined the skirm community. And from my point of view 99% of the players in skirmish pub games are hardcore veterans and the skill level is super high. And they demand nothing less than a perfect teammate or they will get super annoyed and will ***** all over the place if you team damage or tk by accident. I am trying to get friends to join the mode. But, they get scared away because of this. A new player need at least 1k hours playtime in skirmish to just be an average player. But, they leave the mode after 1 hour because of the tone and behavior. What you end up with is a small player base of veterans making the matchmaking system broken. It's a catch 22.
