Mandoble, the P38 is a few order of magnitudes tougher to fly in the MA than any 190. It is just a couple mph faster than the Spit IX, doesn't accelerate as well as a 190, and it is a HUGE target.
DJ- I understand the 'diversity starts with YOU' stuff you (and a few others are saying), but Mandoble's got an equally valid point when he says that what he flies won't have any impact at all on the numbers of spits/la7s/n1ks/p51s in the arena. He'll just die more since he is in a slower plane.
I'm at the point where I just want to know the total number of sorties that each model flies... it seems like at least 75% of the planes that I see are one of the 'big 4'. Possibly that is because of that free trial going on now, I don't know. It comes down to really 3 choices. If you want to be on 'even footing' with everyone else, you fly one of the big 4. If you want to be able to get away from spits and n1ks, but not fly a P51 or La7, you usually fly the german stuff. If you want to get dominated, you fly something else.
P47, P38, P40, F6F, Fm2/F4F, the early german planes, ki-61, well, actually just about everything other than the 109G10 and 190D9 are kind of outmatched in the MA.
A P38 isn't fast enough to catch a P51 or La7, so they can bore N zoom you at will. It doesn't turn well enough to fight a Spit IX or N1K2 (plus it really isn't fast enough to get away from one), so you get screwed there too. Same with the rest of the list above- nobody but a masochist would even try to fly those planes unless they are comfortably tucked in with a horde that outnumbers the enemy.
109G10 and 190D9 are very competitive in the MA, which is why they are a good choice for people that don't want to fly the 'dweeb rides', but don't want to get dominated by them either.
Anyway, that spiel really had no point at all, so I'll shut up now.
