Could you elaborate more on the "too strong" definition of yours?
It is also worth saying that game balance is prioritized to 1v1's then teamgames, that might have been the reason why CPz4 wasnt nerfed at all.
The nerf is still listed in changelog. It was supposed to happen, there isn't a reason it just a mistake
I said why it's too strong, it buffs allie units. You can easily nerf it in teams without touching it in 1v1. Make it effect only your units...
