Besides zeb (who's pretty much designed to be an endgame crutch to save you from being tabled quickly) all the phantom 2 are going to work better out of the ghost.
If you want the rear arc spend the points on torps+EM instead for half the cost. ( The ghost can use them out the rear arc without a docked shuttle)
I could see fringe use as a "drop pod" in round 2/3 to make sure it misses the initial furball to avoid damage or if it cant keep up with the movement on the ghost to be on the far side of the table.
