I don't think the ORE part is confusing it's the carts with the randomness and the degrading. Trying to figure all that out sounds confusing. But as I said in my comment some people love all that stuff so I guess some people will love it and some will hate it.
Its not confusing at all. The game is exactly the same. Instead of MUT, you'll get ORE and there is a provision to convert it if you wish to do so.
