I'd agree a lot on this statement. I mean, they made Rose do regular damage instead of reduced damage on the Z-Mech and they are putting too much nerfs onto the Imp. I don't know why Popcap decided to take the support feedback. The players could use Peashooter to counter the Imp due to its splash damage or Rose because of its lock-on and Time Snare.

My guess is that on release, the Imp will be the worst character for the Zombies Team until it gets a good buff.

Thankfully, the Z7-Mech did not get nerfed this patch, so my guess is that the Z7-Mech will be the most common mech due to having similar capabilities to the Z-Mech.
