This is great, but what I think would make Torghast not hated by everyone is IF THEY made it not mandatory, if they are going to have soul ash make it obtainable from everywhere.You get people to do it by giving it exclusive unique rewards.If you could NEVER mount in the Maw except with that mount it would be cool. Mage Tower/Challenge Mode quality transmog, etc.
I really like Torghast, even with %^&* anima powers you just stomp with every class. More Torghast is always a good thing.
