It's simple: Make more dlc characters that are super OP so everyone will buy them. Everyone will complain about them being OP, and after a month of them being out, SSM will "listen" and nerf said characters after a ton of people already bought them. Of course they already knew they were in desperate need of nerf. It wont matter who the characters are, i mean, look at raiden or e cole. Few wanted them in this game but tons of people play as them cuz theyre so good.
