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.
