Actually, we (as in, the [RM]) very rarely go to Hamburg lately, unless there is an incursion to deal with or a raid to be made. Sure, our RP points otherwise, but we actually spend time with patrolling the whole of Rheinland daily, key areas being Berlin, Frankfurt (don't ask) and Stuttgart/Omega-7. Although when I'm on, all the systems are given a throughout check unless we get pinned down somewhere.
What you said about the Synth foods actually applies to most corporate factions. One or two bases, low activity, open conflicts with the lawfuls of certain Houses. But yeah, the fact that Synth Foods doesn't have an own base when they supply half of Sirius with food kinda limits our opportunities. That's exactly why I suggested the LWB going a bit away from focusing on the Synth Foods and helping the Hessians out in the Omegas, in exchange for turf to pirate on.
