Lol. Check out my thread titled.. why do the devs hate gdi. I find that its actually nod thats op. I have much easier time wininng with nid than gdi. Because gdi is just so slow and nod has too many options. Anyway, to your points...
Pitbull vs bikes: both have advantages and disadvantages. Pitbulls win against bikes but cost more and are slower. Any pro player will tell u, speed is just as much, if not more important than combat toughness in tbis game. On the plus side, they can fire while moving. But than again, they cost more.
Preds vs scorps: preds beat scorps, but the game isnt just between these two. Scorps are overall more useful than preds due to higher speed and firepower. Of course this is a subjective opinion, but this is a majority opinion evidenced by the fact that far more people use the scorp than the pred. Just check cnc tv and have a glance at how many nod decks have the scorp, then check how many gdi decks have the pred. Youll find that scorps are more more popular... for a reason.
Inferno vs kodiac: how someone else mentioned, these two should not be compared. However if you must compare them it needs to be pointed out that the Kodiak is only effective against vehicles and base while the Inferno beats almost any ground unit including zone Troopers, cyborgs etc.
But why stop there? Lets compare the mammoth with the avatar, wardog with the wheels, the inferno with the orca bomber, scarabs with the mg unut. Avatars are very popular while mammoths are rarely used. Guess why. And i strongly feel that the wheels need nerfing badly. They make thre barracks totally useless and can be spammed so easily.
