CPUs definitely don't do anything human like at all. Especially with level 9s, it's more a matter of punishing then anything else.
With For Glory you'll at least learn human tendencies that can be applied to tournament play.
i do agree cpu's don't do the average tactics to each character, but they definitely do sharpen reaction time, which if you can land hits against a level 9 computer, you can land hits against a regular person, AND it gives much more incentive to bait airdodges since they'll get the landing lag and you won't (assuming you used a move like mario's uair)
i've been playing against a level 9 & 6 computer team when i can't play on the wiiu and i've gotten much better with ganondorf by doing that
