I understand the need to have people have a level, but I am concerned as it would make this seem a little like a board game.
I really like when people have different power levels, but it's sometimes best when they get to choose to have a lesser hero, not because they started out later or make fewer, but longer posts.
I will keep an eye on this rp, but the stat system does put me off a little bit.

Your opening is good however, and it is clear you have given this a lot of thought, so I will give this some thought too.
