Post what?
What thye have fixed, amended?
Panzer IVH: The added the hull gunner position, although it is a sloppy adation, they dident model the gunsigt for it, but it is very usable, I even get some kills aganst aircraft with it, totaly unrealistic but hey, they added it after several post's were put up requesting it, some of which I started.
La-5, La-7: Bomb load option was added and an attack function.
N1K2-Ja: They added the larger ammo load which the plane had as apposed to the lighter one which was the only choice for a long time.
MC.202: Improved ROF for the 12.7mm Bredas added after post's indicated somthing was porked.
AR 234: Added the 20mm Gun's, be nice if they did a sight though.
Typhoon: added Drop tanks
Metric bomb weight issue: They corrected the pound metric equilvency that was hampering metric ordance from being as effective as it should be.
Attack mode: many planes modified to have an attack mode, most notably the JU 88.
Preformance tweaking: All allied plane are now better than they shpould be.
Did I say that?

Most all of the above were the result of people posting about issues they had uncovered, their are more I am shure these are just the ones I can remember off hand, also preformance issues have been adreased in the past based on findings and on Whining, the NiK2-J was neuterd do to constant whining by historicaly chalenged players.

HTC does listen to people this is a fact, and they are not above admiting a mistake and corecting it, the list above shows this to be so.
