Another related question:
Does the tip-off you get vary depending on the faction you get it from? Or are they all completely random, such that you can discover all existing tip-offs by grinding (ugh) one faction?
I was told the tip-offs are randomly generated and held in a database (much like regular missions) and then, basically, handed out one-at-a-time.
Thing is, if a bunch of people all trigger a tip-off at roughly the same time, they'll all get the same tip-off - which can lead to a bit of a "gumball rally" to get to the prize.
More likely, though, is that only a couple of people will ever trigger one at the same time and you won't meet them because of instancing and, of course, that you might not go after the tip-off at the same time.
Might be fun if there was some kind of "super tip-off" which was, say, sent to every commander who qualified at a random time each day.
When you got one you'd know that the objective WAS worth the effort so you'd be willing to go after it immediately and there'd only be one "prize" for whoever got there first.
And so would everybody else who received it, which could lead to some jolly japes.
