I know it's not exactly the right time, but I think the group concept is good, if we revamp the execution.
-Allow space fighters (let's face it, a battle in space is a battle of orbits. You're in orbit whether you like it or not, which pretty much eliminates any tactics whatsoever. So, if we toss out orbits, we can chuck in space fighters, right?)
-Stop the eternal "War of attrition" where the UNE holds on for two CRs before the 3,000 strong COP fleet arrives and "Saves the day." COP rejoices, and the UNE goes "So, where do we go to lose, er, fight next?"
