Since you are confined to rheinland, I'm not sure, but I have found just logging on with my character, and suggesting we raid the noodlemunching barbarians or trap the corsair rats in their holes in omega 5 will rouse a good amount of activity rather quickly...
Any sort of combat experience, especially when led by the faction leader, often attracts many, many people. If its activity you seek, and excuse me if you're already doing this, a regular presence from the leadership will help bring it out. Even more so if you give them something to do.
I do know of one specific snubnose that is running rather amuk, and you may want to try and recapture it.
