Maybe make a tougher version of GV in which 150 people can farm good EC?
I'm not sure if this is even possible, and if it is, it's gonna be hard to make, but I believe once you hit 150 and get 150 eq, normal GV becomes obsolete because it doesn't give that much EC compared to farming in NS or other kinds of events.
(I might be wrong though, I think some changes have been made to GV since I left)
