How awesome would it be if we could separate between good and evil karma, and they would each provide different special attacks we can use on plants in battles once a day or something.
Like a certain level of evil karma provides a boost in attack while good karma provides a boost in defence.
But, how would we get evil karma? We would have to get a dislike post button or something like that, and -3 karma for being the first one to tell a noob to fuck off.
I don't think you get how Karma works. You don't need to be rewarded for having a lot of Karma, the Karma is the reward itself. It helps you live a complete live. It makes people like you. It makes you happy...
