All I want to know from deep dive is if we will get regular content patches, so every expansion will have 2 more raids besides basic one and new features.
If yes, then it's all right.
If not, then they sell us glorified patches 90$ per each.
Metzen tried to sell the idea of the story being too big for one expansion, but from the description of each expansion they seem lightweight on story and characters.
Three main characters for the first expansion.
Basically just Quelthalas for second one.
Northrend for third.
This sounds very sketchy. Nothing In them sound like something that in combination would be too big for one expansion. In fact by the description all three would have fit into whole Legion expansion, except cost 90$x3.
