so....... a 67% efficiency in the Axis cannon when compared to Allied is then justifiable? 1 mine round penetrating stressed skin and exploding within the airframe would cause considerably more damage than a kinetic energy round ever could, n'est pas? Yet it does not. Not in AH anyway.

You know what irrespective of what may have occured with the actual ballistics the game will be whatever HTC decides it will be. LW aircraft had ammo counters. Allied did not and resorted to placing 5 tracer rounds in each belt to notify the alert pilot that he was down to 300 rds per gun.
We have flaps on the 190 not being able to be deployed exactly at the speeds that the handbook said they MUST be deployed. The arguments back and forth are ad nauseum.
When someone (in oh Germany let's say) comes up with a more playable game and has faithful modelling for all countries represented in that venerable conflict then perhaps HTC will need to be concerned. Currently they don't have much credible competition so they may do as they deem fit.
Aside from all the grousing I do, I really enjoy the game, it just could stand some improvement on the modelling issue IMHO.
A player that hasn't been on line in AH for sometime advised me to check out WB again. It was reported that the CT arena there (or whatever it's called) is seeing between 50-200 players most nights and that the modelling is much closer but I have yet to play WB lately so I can't say for sure.
