Mor Dhona and Idyllshire aren't even really cities, tho. Mor Dhona is more an outpost/settlement, little more than any other outlying aetheryte location. Idyllshire is pretty much the same, having previously been abandoned and now re-occupied.
And adding anything to Eulmore would've had to get around the lore justification. Until liberated, you wouldn't/shouldn't have access to any of that there.
