Agree with most of this but i'm on the fence with wiping peoples records though, like you mentioned moving somewhere else, how about keeping them on the person profile page and instead of having the exclusive rankings that used to also show on a persons page, use that spot (with exclusive battles being removed) to show the members new rank per the reset?
So on the left of their pro-page will display their rankings from sign up to reset and then beside that on the right their new/current rankings...?
As for titles people have won, can keep them on their pro-page as well and have them removed from forums posts and battles?
Other than that, pretty solid.
