You mean "been getting shot down by" hizooka armed planes, Wilbus?
Seems more a complaint than an observation. (by pacifica, I mean)
Pacifica, if you don't want to die, stay out of their guns!
Seriously, though, flying the 109s, 190s, c2s, ki's, zeros, yak9u, la5, n1k2, and most planes that are NOT british or american, you really have to land a lot of hits in one spot to bring the enemy down. They can take grazing hits 2-3 times and still remain a combat threat, often. I myself have soaked up ungodly amounts of enemy fire while in bf110s, ki84s, p47s, c205s, and ta152s, at times. It all just depends on where you get hit, and how hard you get hit.
