Zac OP or nah?

zac is as good as his team is, if zacs team fails, and he couldn't win the game for them, he will struggle, great setups and CC are nothing when your team cant capitalize on them.

I depends 100%. He cannot carry at all, he can only help real carries carry harder. That being said, he has great tools for that. He has an engage jump, which helps him gank from unexpected areas. He has great sustain in jungle, imo. 3/4 of his abilites are some form of CC. All in all, only go Zac if your team is competent enough to let themselves be spoonfed ganks by you.

He has the most ridiculous ganks ever, jumps in from a thousand miles away, CCs you and kills you.

Complete nightmare to be laning against, but his damage doesn't scale well enough so he can't carry if his team sucks.

Most of his kit is reasonable in regards to how he can cc/disrupt the enemy team.

Everything except his dash.

It is **NOT ** balanced. It's too easy to setup and the speed he travels is absolutely bonkers.

One of those two things needs a nerf.

Or, better yet, make it so that the distance he can travel is proportional to the time he spent getting ready to sling.

Give it the Soraka treatment. Close slingshots are quick, whereas longer ones allow you to travel farther (but slower).
