I've seen a lot of 0 chemistry challenges done this weekend from the pros in champs. I've always said shouldn't ultimate team just bin chemistry off completely? Then you can actually have your 'ultimate team' instead of forcing players you don't actually want to use but have too for chemsitry. Playing out of position and that working is a big no no for me though, they can do that with the crazy promos at the end of the game cycle.
