If PVZGW2 was to get 1 final update can it at least be a balance update?

Hello, I know pvzgw2 getting a update is a long shot but can we at least get a balancing patch or something? Electro Pea, Z7 Imp and many different characters are absurdly broken and the community abuses that. I think the entire community would really appreciate that. These small changes can really make the game feel a more better.
