I would love a way to be able to take care of your plants with out having to log into W101. I have 6 farms I need to tend to and I also work... I can't log into W101 while I am at work but I can do KI free games.
Plants don't need to be taken care of while you are away as long as you took care of them last time you visited your house. I could see them adding games for it for extra rewards maybe. There needs to be some other benefit on top of taking care of them though.
It would be really nice if there was an app that let you take of your pets needs. It would have it's own spells that would probably cost more energy than in game because it's more convenient and it would only let you take care of plants, not revive any, plant any, or make plots. That would be cool.
