PvZ 3 idea instead of plant leveling

while I don’t mind having to gain packets to unlock plants I absolutely hate plant leveling so an idea I had is instead of leveling up plants  you can upgrade a part of the town when you reclaim it for benefits and this can also play into the customization theme by some decoration giving players a choice of which buff to gain but upgrading the area itself would give better benefits but the obstacles would give smaller benefits. Also you can you fragment or shards or whatever to upgrade the main area and to give players more freedom make shards that can be used for any location.

etc

example of minor benefits

small amounts of seed packets and fragments per day

sun produces 3% faster

first zombie that enters is chilled

start the battle with a puddle near your house

zombies take 2 seconds longer to spawn

major benefits

additional seed packets

start the battle with additional sun

start the level with additional sun

gain extra lawnmowers with a cooldown

gain abilities that either cost sun with a medium cooldown and/or just have a long cooldown

all plants gain 20% attack speed for the first minute of the level

etc
