What are the Tornados doing?

I look around the world, & I see Illustrious & Ark Royal with no Harriers because they’re busy in Afghanistan, etc., serious concern about whether the Harriers will last until F-35Bs start arriving, because of the use they’re getting, & the RAF planning to send Typhoons (still with limited A-G fit) to Afghanistan. And I think to myself – “Why aren’t we using Tornado IDS instead?”. It’s our most numerous combat aircraft, it has a wider range of A-G weapons usable at the moment than Typhoon will have when it goes out there, & if we really need to stretch out the fleet we can probably get some German surplus, since they’re cutting back numbers, which isn’t an option for Harriers.

Why wear out the Harriers, why send Typhoons, when we have planes designed for dropping bombs & just about nothing else, not carrier-capable, with everything integrated, & (relatively) plenty of them?

Your thoughts please, gentlemen.
