Define test bed?
Define new level of damage for WW2?
You will not get WW1 type "holes in the skin" (you know, the kind that IL2 goes WAY overboard on? IMO that's ridiculous and I'm not going to be missing it) on WW2 planes. This is from Skuzzy in response to whether or not we skinners need to worry about redoing skins this way (it is more complicated). The answer was you won't see that in the WW2 planes and don't need to worry about skinning it.
However, more parts, we will see. We ARE seeing. Rip an I-16s wings off. Notice a lot of inner structure? Not all that long ago, when a wing was gone it was simply missing, never rendered. It was a pleasant jump when that changed to a stub of a wing with a 2D bitmap inside. Then we started getting little frameworks (flaps, ailerons, elevators), and now we get full inner structure showing on new planes like I-16s when you lose a wing.
Did you know you can blow the landing gear doors off of a B-25C? Without affecting the gear? What about the most visible recent change: Individually-destructible H-stabs?
We have come a long way and continue to improve. HTCs comments at the time of the WW1 damage discussion were (I believe) related to the NUMBER of parts that could be damaged, as in a wing with 3 parts would instead have 10 parts, but not that the DAMAGE would change... Just how the game shows it and how it might affect your gunnery tactics (needing to concentrate fire more than spraying away).
The changes you are asking for are being implemented. They simply aren't being recognized.
