Any bets on who is getting reworked after Irelia?

With irelia's rework coming out soon, it's time for us to speculate on who gets the next big fix.

So who needs it most?

I almost want to say Ivern because he's got one of the lowest pick rates and win rates in the game. However I don't see riot giving a big VGU to someone that new. Morde needs work and even his mains are giving up on him (at least riot could revert is last big update). Malphite needs TLC and looks hideous. We can also never forget about ryze because he gets a VGU every 6-12 months; I'm pretty sure he's due.

So I'm going to guess that Amumu is going to get a rework next. He's popular but older. At the least he needs new visuals. This would also give riot a chance to decide on if they want to keep grenade Amumu or not.
