IIRC you didn't see their colors, or yours, in the first one- all the time at least. It was supposed to be set up to see the other person's customization but part of it was bugged and didn't always work, leading to the color you see on screen having nothing to do with the one either of you selected.
what would you think if you were able to knock your enemies weapon out of there hand? force them to pick it back up. and i think they should bring in hand to hand combat. that would also bring in more moves for the warriors.
