I'm in. 

I'm not fond of the cap. Devil Fruit is half of one piece's world. I can see if it was a small crew if this get big to like....12 people or more, a small cap such as 3 is rigid. Play by ear. 

Though I'd rather see a cap on logia and mythical zoan. Don't outright ban them but instead impose restrictions that can be released throughout the rp. Such as logia intangibility is only for when you master your powers but that won't be till people can use Haki. Depending on where we start in power. Or say with a Mythical Zoan, one can't go full form and the healing is heavily nerfed until once again we are farther in the rp and have evolved enough to handle such things. Everyone grows side by side.
