The Mustang wasn't as widely utilized as long as the FW so it stands to reason that there would be more FWs. There has to be to make ToD viable.
What other P-51 could you want?
The two main variants are there (D and B; even if they add a C its still just a B).
A P-36 or P-51A maybe but there should not (and I suspect wont be) an 'H'.
Where in a '43 ToD theater will you have to 'out run a Dora'?
As for the P-47s what's the point of an M (especially the M) or N? What P-47 can't out perform the best Japanese plane now?
If HT wants ToD to be a success and draw new players then he can't afford to play 'substitution roulette' or play withe made up aircraft match ups like you see in the other events or in the CT.
He will need an earlier (A3 or A4) FW, and an A6 (4 X MG151/2cm). He will need an earlier P-47 etc...
He will need a Spit LF.MK IX. He will need a whole host of Russian and Japanese planes. Like early yaks, laggs, A6m3 and any number of planes you wont ever see in the main.
The type of folks who will have an interest in ToD aren't necessarily the players HT has now. These folks will be coming from the box games. Where the planes are o'plenty. Where they can set up a 'believable' on line war with out all the hocus pocus need to pull an event off in AH.
I am not sure what HT has planned or is thinking but as some one who knows and games with a lot of these types of players I know they won't be convinced to give it a try unless it is decently put together.
Some of you may only think about what you can fly around in the main (and there's nothing wrong with that) but the average main player won't be too excited over ToD just like he/she isn't interested in the CT or other events.
Just putting together a 'code' (scoring, tracking, missions etc) to make ToD work won't be enough. Any number of box games offer this type of 'code' already.
