Future Plans for Ryze? Rework or Just Balance Tweaks?

With some major Ryze balance changes up on the PBE right now, I think a lot of players are wondering: do these changes reflect a decision within the design team that Ryze can be fixed with just balance changes? Or is this a temporary fix until a more thorough rework can be done? Any chance a Rioter like Ricklessabandon or Repertoir could drop us a line?
