I've been sat (docked) inside George Lucas for about half an hour now just watching him (he's in a Viper - 4 missle racks, 2 chaff). His shields don't seem to be infinite, they do go down while under fire from the station (but very slowly) and he's able to recharge them again. He also seems to be able to recharge fully by lurking at the back of the station during periods when it gives up firing on him (why does it stop firing? is the station response for a limited period only?). He's also not alone - he's got a mate (or perhaps just another commander who was able to play him at his own game?) in a Cobra. The two of them were fighting and ramming each other inside the station for quite some time. Saw him dumbfire a player right in front of me (sorry mate whoever you were - tried to warn you but I wasn't fast enough) - and two more while I've been typing this.
I don't have video capture but I've grabbed a couple of screenshots.
Edit 1: he's not indestructible, he just got blown up by the station!
If this specific episode was not such a painful representation of FD's abject incompetance in managing their game space, it would be comical. But to allow an individual to park there for the better part of a day and do this is a pretty good indication of where FD is taking this game....right into the toilet.
That is incompetance at the highest levels, and propogated through the entire organization. Heh, I think you can drive the final nail into the online portion of this games' coffin.
