[@VitaVitaAR]Fair enough, although that's the assumption I was working under rather than the other way around. I was just kind of assuming that summoning would end up going much less like Stay/Night and much more like /Zero, without crazy blue men in tights trying to stab the summoner in the heart and all that. So, since it's unlikely other masters would be involved in another servant's summoning, I thought a co-op post would be the best way to get it out of the way and settled clearly.
