I fully agree with under damage modeling. That particular Yak (flown by AI) still flew and fought for another few minutes. It went down after wingman 190 collided with it. Yak was torn in two, while 190 lost half wing.
Still, damage model should not to be discarded so easily. Progressive damage like engine fire come to mind.
Gunnery may seem hard because you don't get much visual feedback. In AH you are used to get feedback on hitting with even .303 at 1000 yds - same hit sprites as with 75mm HE at 50 yds

.
Yes, Il-2 has few things to learn from AH still. But AH has couple of things to learn from Il-2.
Personally, I find it hard to go back to 1980 style cockpit, imperial unit system in LW planes, star wars hit sprites, Linda Blair 6 view, binary damage system. If they fixed these things in AH, then who knows

P.S.
Hi Santa ! How's school ?
