Frontlines type PVP should never be FFA style with an odd amount of teams.
-A solid strategy for winning ANY FFA style game is way more complicated than when you have a single opponent. It is way too much strategy for an alliance of PUG people to orchestrate. It just turns into a huge giant cluster.
-Fighting other grand companies makes no sense in the context of Eorzean politics and does not leave any room for open world PVP.
-3 team grand company PVP means that I cant PVP with friends who belong to a different grand company which is completely absurd. We made our grand company choices when there was no real difference between the GCs.
Please reevaluate how future frontlines PVP will work this way. There is now a solid base of coding and PVP balance. There still needs to be large changes, in my opinion.
