Not sure if there is a best way. We use DKP also in my guild, we also have alot of PvP players that have arena teams. I'm only a occasional BGer. So I think your GM should defer it to those that can use it the most. In VoA, we don't have to use our points except on Tier items that drop(PvE). I know most of the items(guess rings excluded) are class specific, so if it was say a warrior piece and one of the other warriors in my guild that PvP'ed more needed it I would certainly pass. But that's sort of on your GM and guild rules you guys go by. But some people are greedy and would rather have it, just to have it then actually need it to use.
