Complaining about getting turned around in a Adv. Train? Ever tried to do a mission on a Geb with ~20 NPC Fighters hitting you? It's no fun, I tell you. You could get seasick.
But, I won't say I don't like having NPCs around. It's very annoying for a trader who's going near the Nomad-Systems (Kappa, Delta, etc), but it makes the systems a bit busier. As long as it doesn't effect server stability or lag, it's good I think.
