It seems that no matter what happens, someone is always going to take advantage of the design. It really shows that pvp is designed for CC and not FL, where you can have a premade of 4 Summoners drop their Bahamuts on the exact same spot. Or 3 DRKs pulling you hither and yon while DRGs drop on you from above. Perhaps the best way to fix the issue short term is to do away with 72 player battles and go with 24.
