Would add a slight flavor and shouldnt be such a overtune, to see who has
created a dimension door I happen to stumble upon one, and other thing, the
ability to sense you are about to be summoned, even at 1% ratio and only the
info someone is trying to summon you or so. these of course available only for
the bestests of the level 5 navigators.
or add a rank of master navigator for those who do certain amount of
navigating, sorta like a rep system.
giving rep for casting summon is a wee bit dangerous I'd say. Would you like
people trying to grind reputation by summoning random people?
For the dimension door, you can already use track in the room to see who has
been there, that is probably enough.
