I haven't played in a while...  But what is this ENY problem?  My Yak never had this problem.  Nor did my D3A...  Or that Spit 1 I flew every now and then.
Hmm... I got nothing against the more powerful late war birds.  They're good, they're d*** good, and with a good stick some are nigh untouchable for a rookie like myself.  
But you'd think that a bunch of grown men could just suck it up a bit and fly something a bit weaker.  Your pony-D unavailable?  Fly the B.   Your LA-7 unavailable, fly the 5. 
 If you fly it cause it has special meaning to you, and it's unavailable, fly something else,     You never know, some other plane might catch your eye.  I never even knew what a Yak was until I decided to up it because I got tired of the F4U.
