The only problem with PvP is that they only offer PvP rewards.
Shoud they have put allied seals in it back when the hunt was created, everybody would have queued for PvP instead of waiting for several-hour long pop.

Besides, the population in three GC are not that far from each other, so there's no reason the GC requirement makes the waiting time that long. People...just...don't...want...to...participate...enough.
