Love your ideas, just a few changes I would make.
E.M.Peach's stun should ONLY work on Z-Mechs. It can still damage other Zombies, but not stun them.
Add toxic aura to Druid Rose.
Decrease BBQ Corn's firing speed.
Decrease damage reduction while using Pea Gatling, Sunbeam, Big Bolt Blaster, and Cannon Rodeo.
Increase ammo for Cannon Rodeo.
Decrease armor and increase cooldown on Barrel Blast.
Change spikeweed back to the way it was in GW1, where it took a second to arm.
Give Super Commando his 4th bullet back, at the cost of damage.
Don't buff Tank Commander's damage on a direct hit, but do increase splash to 30.
Increase Centurion's clip size.
Don't buff Super Heroes laser damage. Instead, decrease the heat generated, allowing them to fire longer.
Increase Cozmic Brainz fists damage.
Decrease scattershot radius and damage of Deadbeard and Partyman.
Increase scattershot damage of Flameface.
Buff Sharkbite's scope impact damage, to make up for the loss of splash damage.
Revert Computer Scientist's Crunch mode to the way it was, but reduce his reload speed.
Don't increase Long Bomb's damage, but do increase the splash radius.
Increase the effectiveness of the Super Meter upgrade for Disco Chomper, Computer Scientist, and Iron Citron.
Other then that, I agree with the rest of your list. Let us make this game great again in its balancing ways.
P.S. I appreciate you taking the time to defend the points I was trying to make on my posts.
EMPeach would then be useless otherwise if it only stunned Z-Mechs, unless it destroys them completely. It already has an arm time unlike the Sonic Grenade. I think of it as having two uses. Like how the Sonic Grenade also drives the Chomper out of burrow, the EMPeach is a mega stun for the Z-Mechs. Also Captain Sharkbite and Captain Cannon are the only ones who have splash damage, so I don't think his impact damage should be buffed more.
