It's not that Zoe has too much power, but rather an unproportional amount,
Yes, her E and Q are ridiculously strong, but her ult and passive are pretty lackluster compared to other champs modern times. Her W is an rng table, and THAT has problems of its own. If you take her kit as a whole and mash the numbers together, she doesn't end up doing that much more damage than a regular mage with their full rotation.
She simply just have too much power jampacked onto E and Q.
One of the most common comparisons you see is between Zoe and old Nidalee. Old nidalee relied almost entirely on her spears and heals, which were also 2 basic abilities. Another example could be Blitz. Land your Qs well, and you can completely turn the tide of a teamfight with a good pick. Miss your Q or hit the wrong target, and you're not only useless, but also possibly detrimental to your team.
You'd think they'd learn about how much people hated those types of champs. Zoe could've been an experiment to see if that kind of kit could be reintroduced in a healthy manner into League again.
The problem with many of the ideas based around nerfing her Q and E are that Zoe's niche is based around those two. If you nerf those, she won't do anything.
In my opinion, the problems with her kit could be solved through:
- W RNG fix (multiple ideas circulating around boards)
- Less emphasis on Q and E, and buffing passive/W/R in other ways to compensate.
seem to do pretty well against her. Just land your main damage and she's basically forced out of lane. Seriously. On new accounts
