What I really hate about the Zac and Maokia reworks
It's that they seemed to have gotten reworked for no other reason than they were to good and just nerfing their numbers wouldn't work. Shen seemed to have been reworked for a similar reason. There was no good reason for Zac and Maokai to get reworked over other tank junglers who need reworks a lot more like Nunu, Rammus, Volibear or Amumu and I know Rammus has a bunch of changes on the PBE right now.
