You use Eagles, why not also use the Roc MkII when 4.85's ready? Likewise, I'd think you could add the Griffin... y'know, when it stops sucking. Right now it's just like an Eagle, except worse at everything.
Well notice that their bomber section says; "(While we wait for our own, or the IMG bomber)" That says right there that they will be using the Roc Mk II, provided the new version is better than the current..
But yeah, they need to replace ALL the Tigersharks once that new Griffin comes out (provided its not a flying brick anymore.. [Greyhound > Griffin in agility..])
