I see level sync as no different than having separate queues for WoW battlegrounds based on level brackets. Unfortunately, there isn't enough interest in PvP in FFXIV to divide us into i50, i70, i80, etc. brackets so we all have to be playing in the same sandbox so to speak. Perhaps if Frontlines garner enough interest and enough participants, they will be able to open up different brackets in the future. The thing that gets me - and I will continue to reiterate this - is that the level sync in conjunction with the morale deprecation punishes everyone who worked for PvP gear in preparation for Frontlines.
