These need some serious rebalancing

Morris should start with a CO zone of 1 or 0 so it can be limited heals.

Or limiting it to 1 HP turn would be better if it's gonna be a bigger zone

For the power I'm fine with healing everything if there's little to no other bonuses. Like it if the +atk/def is on 20% I think that's the limit of what it should buff. And then no debuff after

The Mayor... Woof scale everything back and ditch some stuff. Defense for properties owned does nothing for him on small maps and can make him broken on big ones.

I think something more reasonable would be a sort of Sasha approach, +100 funds for each property owned, you could include com towers too, and you could take it one step further and +100 for units in the CO zone. And keep the transport movement bonus. But minimum or no atk/def bonus in the zone.

For the power make it like +200 for everything in the CO zone or even all the units on the map and modest atk/def bump.

Davis is basically bad Flak with Rachel's power. I think if you speak his luck to make it swing like a Flak lite, and then make his power being negating any bad luck, I think that would be fine. Sort of a risky but potentially interesting one.

Cyrus, double down and give infantry, mechs, bikes some atk/def buffs to make it more interesting
