I don't really care that much, but have to agree it's quite a stretch to say there is no lorelol in goblin and worgen DK's. I've yet to see one in game afterall. It would have been much easier to swallow if they had thrown a few into ICC, but they didn't.

The goblin race that joins the Horde is from the Lost Isles, and joins for a specific reason. If the profit margin for going Horde is good enough for goblin DK's, why do the rest of goblin-kind remain neutral (Booty Bay, Tanaris etc.) Also, if a goblin (or Worgen) DK goes to their respective starter area, the quests will more than likely treat them as islanders (or Gilnean). I doubt the quests would be written specifically to exclude them.

The worgen that join the alliance are from Gilneas, which is still behind the wall when Battle of LHC happens. On what basis would non-Alliance worgen from Grizzley Hills join the Alliance after becoming DKS. I don't see them making the decision just because of the Gilneans.

But really, no matter how Blizz swings it, they could have put in a couple token scourge goblins and worgens to make it more believable now, instead of the mass of them that will suddenly appear on expansion day. Where have they been hiding since the start of WoTLK? Were they the Lich King's secret weapons that he forgot to use? Why are they not currently working with the Ebon Blade, but suddenly will be after Cataclysm?

Again, I don't really care that much. Gameplay means more to me than Lore. I'm just saying its stretching the Lore to make it happen.
