If any semi-hardcore or casual (but coop / boosting friendly) team captains would be interested in exploring the possibilities of cross-team networking, send me a PM.
4 is a small roster, so I'm hoping to coordinate with a few other teams so we all have an easier time setting up coop / boosting sessions, and we know what everyone's playing to coordinate when to get those games to run sessions. (On a much more organized level than posting in boosting threads looking for others)
Yes, this will require "showing your hand" to some rival teams on who is playing what, but on balance each team would be helping the others, so everyone gets helped, and all of us are working to crush PS3T.
If sending a PM, please let me know how willing to coordinate your efforts. Something from "We're willing talk about potential group boosting sessions" to "we're flat-out fine sharing all team communication."
