Krusty, don't hurt your own argument by saying the VIII should be perked with the XVI. The XVI has enough small advantages over the VIII to be treated separately, especially with its 400mph roll rate.
I disagree. The spitfires already retain too much E as-is, they can reach and sustain what are IMO unhistorical speeds. I had a spit9 dive on my f4u4 and I was diving away already. He followed me to the deck, closing. I was pushing almost 500mph and he was still able to roll to stay behind me.
Spits don't use high speed as defensive moves. They use it as attack moves (chase, dive, pick, etc). To evade anybody they just (out)turn them. Roll rates at 400mph are mostly defensive things, and as a person who's flown more than his fair share of 190s, I never really found it all that useful at higher speeds. It's the low speeds that roll rate is more important, for scissors and such.
Oh, and.... Don't get me started on the BS that is "bombers" in this game!!
They are the B-1B stealth bombers of modern times, outrunning most fighters, no engine overheat, airframes WAY too sturdy, pulling BS manuvers, taking 25% fuel so they can accelerate, climb, and run faster than they EVER could historically, and they can enter an enemy radar at 15k, bomb the field, and be out the other side of the radar inside 5 minutes or LESS, in which time most planes can't take off and even climb up to them, let alone get up to speed to chase. They are nearly unstoppable surprise bombers, which is 1,000% a-historical for these big formation-enabled behemoths.
