That dish looks like someone took the glowy side piece off of a galaxy class nacelle, put it in a frame and glued it to the front of the boat.
I see a little nod to the connie refit though. That side piece on the left of the image.
As for the AFK thing, I really think that it will have no effect. If what they say is all that they are implementing, then leechers will only need to move a little bit now and then to get around it. Maybe join in for a second or two, then fly back out.
Stopping lunges against low flying enemies is a bit crap though
