Your post sucks.
Kat doesn't have bad zoning. You don't even want to zone the enemy pre-4 and by the time she reaches level 4 she can do just fine.
Same thing with wave clear. There is no point in having wave clear pre-6. At all. Ever.
None of your nerfs are even viable nerfs to Kat, so I'm not sure what your asinine post even tried to address.
