I never argued they should? My argument is that if you're playing at weird ass hours then maybe it's time for some introspection about how important a MMO is to you if you can only play at strange hours. Further, while Blizzard should want to have as many subs as it can within reason, if you're arguing that you need the RDF to satisfy your degenerate play times then maybe the problem isn't Blizzard.
I digress. I think we may have both misunderstood each other's arguments on some level here, apologies for the hostility.
