There are 6 winners in every team type game, even if some of them do nothing to help with the actual win.
Its no less fair for the top players in ffa to get some kind of credit. And as I said you have to come in first once for them to count at all, and if you get 4th or worse its back to 2nd and 3rd counting as a loss.
If you think thats bad though ......... In mw2 I had a rediculously exaggerated winstreak in ffa due to the way they counted there. All one had to do is play nothing but ffa and every win counted toward your streak. Play another mode and lose and that
was the only way your streak was broken. ..... of course it was the same rules... Take first and 2nd and 3rd counted also.
