I still find weird Horde needs Dalaran at all tbh.
Like, I understand the need of a faction neutral Hub, and that dalaran has been awfully convenient in two expansions for that, but… Dalaran really doesn’t do it anymore.
And lore wise, as far as “city of magic advancements” the Horde has exclusive access to better stuff, they have Silvermoon, the Sunwell, and now they have Suramar too.
And to be perfectly clear, I don’t want Dalaran to be exclusively Alliance at all, it is not supposed to be, it is a neutral hub, I just don’t think Dalaran is important for a discussion to even exist at this point. I think Dalaran is just not relevant to the story at this point.
