If any dev team needs Asmon's advice it's Blizzard. WoW is in a horrendous state because they actively ignore feedback for too long and act upon it when it's too late. FFXIV was doing just fine without Asmon. Is it perfect? No, but is any game?
I think if SE were to seek out advice for FFXIV they should look at someone who does a lot of pvp because that is currently the game's biggest weakness. It isn't given enough attention.
