Fw190A8 does good in places where isn't too many people, but still more than one on one fight.
Though, with advantage theres chance to go 1 on 1 in Fw190A8 against any plane and do couple bounces before forced to run away or try your luck in closer fight with the enemy.
If there isn't enough people around, it might mean you'll just get stuck in 1 on 1 fight and then reinforcements can be enemy sided - then you're in trouble.
If theres many people, it usually means theres those "hawks" at 20-25k floors, who might get fixated at you.
Since you can't really afford to fly above 20k in A8, theres more reasons to avoid those.
If its situation where your side is fightning around enemy field, then you have pretty good chances in A8.
Since you don't have to be afraid of "hawks" and theres fairly constant friendly force coming to the field.
One important thing to remember is to not go too low, where you can't dive to run.
Something like 3000-6000 feets... it can vary alot on situation around the area and terrain.
okey, theres some things that will keep A8 alive for while (assuming he don't need to be told how to fight the fights

)
..with the experience of 278 kills without deaths.
