Well, the question is, whether they wanted Aleroth to be in the game in the same way it is presented with the Add-On - or whether they wanted just to have "more" Aleroth to be within the game - in the same setting like during the main game. The Add-On shows Aleroth a relatively peace, and this is unlike in the main game, as far as I have understood it.
I think there's more to the small word of "more".
