What CAN be done to fix TS4?

I want that they improve the plant-sims. I love occults sims and i loved when they brought plant-sims back in a patch. But, plant-sims don't have any power, and sims only can stay 5 days like plant-sims. I want that SimGurus fix this, adding more things for plant-sims ( like power and the possibility of plant or have a plant-sim baby). I want too that they add the possibily of create a plant-sim right from the CAS, like liens and Vampires, adding also a new type of plumbob for plant-sims. And all that I spoke about Plant-Sims, i want that they bring to ghost too. I want that they add the possibility of create a ghost right from the CAS and add a new plumbob type from then.

Conclusion: I want that SimGurus improve Ghosts and Plant-Sims
