I agree with this, this does seem to be a slight problem with the npc placement. Even though he's round the corner from the boss, people run straight through the boss area to get to the teleport out.
Would it be possible to put in a teleport next to the npc maybe?
When I run through a hideout, noone is camping and the boss is there, I usually kill him and his bodyguards.
If someone is already there, either waiting or killing I don't interfere, run past and say "good luck"
