I still think it would be a bit of a stretch. I think Blizzard should lay off of Old God influences on major lore characters for awhile, I think they are making Jaina violent to give Alliance more bad asses anyways (something we need) so turning her Old Gody would be a bit counter productive.
But yea, it's just speculating anyways. I don't know if they'll do it and and neither do you . Carry on.
