NEVER! This thing killed 3v3 and 4v4 team games in vCOH cuz it was impossible to find any team to play against. So if wanted to play 3v3 or 4v4 game with your friends, you have to go for custom game and then wait and pray till or ever any other random 3 or 4 people will fight. This killed vCOH for me and my friends cuz it took many many minutes to play a game (and after lets say 20 minutes of waiting they got owned and quit in 10 minutes).
Consider how long does it take to find enemy even in 2v2 right now. Separating team and nonteam games in COH2 (game with very low active players) will lead to fast end of teamgames in general.
Lets compare it with SC2, theres no arranged vs non arranged ladders and the game is still fun to play everytime with almost no waiting time between matches. Why is it so?
+1
vCoH has separated arranged team automatch and it's not good at all. It totally killed team automatch there. Also, it's impossible to team up with a single team mate and play a 3v3 or 4v4, with random players filling up the slots.
I think arranged teams work well when you have a huge player base like in Starcraft. For CoH, I would keep the automatch system simple, dividing the playerbase the least possible.
