There's almost nothing they can do at this point, the damage is done with the flooding of the game with tomes and seals.

Not to mention all the animosity the whole thing caused between players on the servers.

Hunts were a horribly executed idea that did more harm to this game than anything, and the next couple of patches may put a few more nails in that coffin if SE doesnt get its head out of its arse and think before they put in more stupid things like this.
