If you don't care about raiding VS and want to exp you can leave the guild until he spawns and not participate in the fight and then rejoin your guild after he's dead.

I know it sounds dumb/crazy (it pretty much is) but this is what people do and it is an accepted practice. In ToV people who are ready to complete dragon quests drop their guild and then do the turn ins when the dragon spawns. They get their quest item and do not partake in the fight, rejoining their guild after it is over.
