The PUG servers now have a buddy/foe list which the RWS balancer will take into account. This means if you're buddied with someone and they're buddied with you, there's an increased chance of being on the same team and if you have a foe, it'll be the other way around.
You can buddy/foe a person from their PUG profile, once you do they'll show up on your buddy list.
