The problem with FoV is the XP bonus is too weak to compensate for the very little xp given from Mobs once you hit T or lower. FoV is also designed for 6-main parties, which means slower kills. This is why there's three main hotspots at the moment. All of them being GoV.
~12-32 Gusgen
32-60 CN
60-99 BO
You never have to leave BO for Abyssea because even at level 99, the leeches are EP and thus give EXP, and 4100 EXP per page makes up for the ~1 EXP given from leeches. Granted, Abyssea Worm parties is faster.
The problem with the GoV camps in general is if there's no party going, you're stuck with soloing or asking someone to powerlevel you via pages from Zeruhm Mines or BO. FoV really does need to be updated to make it more comparable.
