Anime or occidental style, I don't know.
I would really pay to watch it. each seasons should be like about each WoW expansion. And an entire cartoon movie about the war of the ancients.
Not sure how many people would watch it but maybe anime style would open it to the public well.
I mean, the great japanese style knows well how to illustrate actions about saving the universe from monsters. And there are lot of tentacles related to the Old Gods.
