I won't deny it, Forever implements some interesting things. Dalaran, for example, is something I'd like to see here in the future, but what I think is closest is seeing Northwind's "sister" zone, Riverglades. I like the layout, the terrain, and the content, and it's something I'd like to see alongside Turtle WoW's already implemented content, perhaps with different quests that fit the story Turtle is developing.
In the case of Dalaran... I don't know, the zone really clashes because the model itself is gigantic compared to the surrounding mountains. I don't like how they integrated it at all. I mean, its tallest tower is literally taller than the mountains of Alterac, which should be incredibly tall since it always snows there. A smaller version would be appreciated when the time comes.
But for now, I think Riverglades would be a very good addition to MoA.
And no, don't come at me with "Oh no, you're going to steal things from Forever," guys, it's the same franchise, the same story, the same world. MoA wants to follow a different line than retail, and taking things from the official Classic+ isn't a bad thing at all.
