Currently, there's a limit to how much you can level up plants. Plants that max out at Lvl 20 are limited to Lvl 5, plants that max out at Lvl 15 are limited to Lvl 4, and pants that only max out at Lvl 10 are limited to Lvl 3. I think it's based on the tier, as that's Silver Tier for each respective level cap. Besides, there are gonna be MUCH tougher zombies to compensate. Brickhead Zombies, for instance.
