they have said they plan to adjust the minimum numbers required and it looks like we will soon have the ability to set custom matches
1v1, or 2v2 etc to get quicker games going
This is already in game. I've been doing 1v1 for the last couple days. Makes doing the PvP dailies SO much more enjoyable. I much prefer playing ONLY with the people I know rather than those 10v10 cap 'n hold matches which can sometimes go on for an hour.
I have no idea when they made the switch as nowhere was it listed. I happened to read about it in the PvP forums and tried it out and it works. Both 1v1 FvK and FvF. I haven't played around too much but it appears you can set up any combination of players.
