That's the whine of a Luftwabble. Just because you don't like RAF birds doesn't mean they're bad. Luftwhiners just don't like to see birds that can take em down 
Lol, for once I didn't mean to insult the spitfire, and people take it in a way that does

.
What I mean is that the spitfire has a high noob to vet ratio, which is undeniable, but it does not get ALL of the noob attention; two slow for some. If we gave it increased speed, there would be no down side to push noobs away from it, and hence it would likely account for almost all sorties of almost all noob pilots, as opposed to what I would guess is 60% of sorties for 70% percent of the total noob poplulation.
