Change Zac Q so he gets 2 casts if he lands the first instead of having to auto attack to apply cc

Where is your basis on this rework? All that you have established is that you played Zac a lot and most likely really enjoyed his kit before the rework. That would explain why you don't like the rework since it changed his most powerful tool.

I feel that you are trying to claim "ownership" of Zac. That somehow all your time played with him makes you an expert on what Zac should be and how he should be designed. However it would be a lot easier if you claimed facts about the moves instead of talking about how much you play Zac. As an example, humans have been using brains for millennia but only recently have begun to really understand how they work beyond "don't let it get hit."

However you seem to ignore the fact that his Q and R were lame moves before that asked the player little more than to press the button. While there were options to put more thought into the moves on the player side rarely would it require much thought and the moves have a very simple flow chart for the player to use to decide how to execute on them. The new Q is 80% buff in my book and his ult is much more engaging in exchange for the raw power of his old one. These are the 2 points you have to argue against, not waste time talking about how much you've played Zac.
