"Does AH actually need Seafire?"
In my Navy you would be taken into chains for saying that, and shipped off to the Colonies...
...but in any case, when the Hurricane series gets "redone" at some point, im hoping for a Sea Hurricane which saw a lot of service with the RN. Also we have the F4F, F6F and F4U, which all saw action with the RN.
But, there is a Seafire already in the Seafire IIc we have, and I dont see Pyro getting rid of it, so it comes down to which is the most usefull varient. I would still vote for Seafire III, based on usage in various theaters.
The Spit V thing is tricky. *If* Pyro is going to add some 1941 LW fighters, then the Spit Vb makes some sense, if not, as you have already pointed out, its a bit of a mismatch vs a 1943 Fw 190A-5 and a 1942 rated 109F-4. Its not the end of the world, because you still have a Spit F.IX there you can use to butress up the Spit Vb I suppose, but a Spit Vc would still see a lot of use in other areas.
The Spit Vb and Vc are so close in 3d model its really a shame not to get both versions to plug all the holes. We may yet I guess, but I think we have to be realistic in that every varient isnt going to be modelled for everybody's favorites. Seeing the list he is thinking about I wont look a gift horse in the mouth.
