I gotta go with Striga on this one. IP was always the most annoying place to go IMO, even with Super Speed or Teleport it took ages to get to those far away missions. It is like the higher level equivalent of having to go to the mission door in the little grove of trees in the far back corner of the Hollows. There was very little reason to go, besides the occasional Lusca hunt, and while the zone had a lot of potential for cool stuff (come on, "The Docks" in super hero stories have always been places of major fights, information gathering, ect) it was overall rather boring.
