I think zac is well designed, I just miss the iteration of his ult where he could kidnap people. My buddy and I would duo bot lane as zac/nunu and just have a blast E + R kidnapping people into the charged nunu ult.
I, too, desperately miss this ult. I mained Zac after his rework and had an absolute blast one-tricking him for a while. When he was reverted I played one game and didn't feel like his old/new ult worked well with his updated kit anymore, and I've never played him since.
I know Zac mains everywhere will be upset with a Rioter for saying that, but man, I really miss the kidnap ult.
