I would become an MP6, but for non conventional reasons. I would become an MP6 only for the fact that it is the next step in the life of Magicduel during the story mode. I would not do it to be a protector, to be a destroyer, or to be some kind of honorary member. I would do it simply for the experience of the next step in Progression for Magicduel and that is it. My steps are purely experimental and to try all kinds of different things. Even if I may fail or dislike the experiments, I still give them a try.
I have not done it currently for the fact that it is not part of my characters personality to ask for help from others. My reasons are purely for Character RP only. Same as why I've never joined any lands in the almost 8 years I've been playing this game. My character is a wanderer looking for a place of acceptance for him. He will NEVER request to be accepted, it is expected of others to try to actually want him to join them and to accept. It has never happened, and I don't expect it to, but that is the way of a loner character. That wanders the lands searching for not only acceptance but also for peculiar things within the world, with the goal to experiment with every clue he can find to solve the worlds, magicduels, mysteries.
