Not at all, I believe you are very much right!! I am a paying player on Nutaku's Aigis so now having confirmed I can by SC on DMM and DMM offers more than Nutaku, well there would be more of an urge to spend there rather than Nutaku, the only saving grace I have that may stop me buying on DMM is my main is on Nutaku and DMM is has more of a constant flow of Free SC than Nutaku's Aigis.
She is a good looking unit so she will indeed be a great addition to my main party.
