I personally prefer the classic system to "CCBS", as I find the pistons and gears to add to the bio mechanical nature of the characters. "CCBS" on the other hand, I find to be rather plain looking.
And from what I've seen of halo 5, it dosnt seem to be getting better any time soon. The major flaw with the "xbone" is that almost every game on it can be either found on the 360 or on another platform, so there's no real push to get the "xbone".
