The F22 was arguably designed for a role it no longer has. The idea at the end of the Cold War when they did the design brief on it, was that it would hang out over Warsaw Pact airfields, and Seal cub anything that tried to take of. Think of it as an airmobile Sam battery parked at the end of each runway and you pretty much have it.
The problem is, even though the Russians today have far fewer airfields than they did, there is significantly fewer F22's than they intended to buy. So its going to be very difficult indeed to find enough (deployed over 2 oceans mind you) to create an air dominance effect. So I can see why they are trying to use them as force multipliers for the 3rd gen fighters. The interesting thing is what happens when F35 enters service, because from what little ive read on the subject, there may be some issues with getting F35's and F22's to talk to each other. There was some clever discussion of creating flying information bridges, which would be able to take information from F22 and F35 and exchange with both. Though if that is true (and if Im not massively misunderstanding the problem) that sounds like a very expensive hammer to crack a nut.
