There would be no need for a probation system if the matchmaking was balanced and the programming would not punish those with good connections and low ping. I don't think the new game will be any better at it since its using the same game engine even on the xbox 1. An entirely new gaming engine would be necessary to correct the issue. I am going to wait and read some user reviews before buying it. Do not fall for the marketing hype.
Knowing IW it will not, it may not even have one at all becasue the on in BO2 really did little to stop or slow it down at all. The same as how the one in Halo: Reach really did nothing to stop or slow it down or make players play the game any differenct than how they were. Punishment systems do not work not nearly as much as some people believe or think or want them too.
