It doesn't matter than "No one asked for Maokai and Zac reworks"
They didn't update them because the crappy gameplay boards community wanted them, they pretty much clearly-stated that they did it because Zac and Maokai were too generalized and did too much, so they try to give them more of an identity to do one specific thing. All-around champions that have it all aren't a great thing to have.
Honestly, all you people do is complain about every change that gets put forth even if you don't even play said champion. League is never going back to the way it was in season 2, sorry kiddos. Wipe those tears now and be happy that Riot is actually trying to address the issues you do have with the new kits, such as fixing AP Support Mao and giving Zac more disruption power.
Hell, they're even nerfing Lee, Ahri and Caitlyn for you.
