Well, you can do it how you'd like, just let me know if you switch out of stats. Also, if I am an Arrancar, I wouldnt care that a person has 100 less stats than me. I'm going to kill him and go all out if they are a Shinigami. Just sayin'.
But yeah, just let me know how things go, and I will join if it is made for progression and not first come first served.
