I’m thinking of new category for this one when I do the speed run for borderland 2 the king Jacobs speed run on umvh. Only allowed to use pure Jacobs guns throughout the speed run any other weapons you pick up you can use it to sell it for money to get more Jacobs weapons.

That's just called an allegiance run. Those are done all the time and they don't qualify as a speedrun for the board. It's too specific.
