I have not yet done them but i had theory crafted a bunch of fits, depending on the number of characters and the burner they seem to be very very easy

Using that spreadsheet you can theory craft an "Orbit X, F1" fit using cheap ships and cheap fits to break the tank (which may otherwise require expensive bling on a garmur)
Just wondering, do you know the ranges the NPCs are from the beacon on warpin, that was really my only concern
