I'm not sure the IL-2 needs to be perked as much as it needs to have its ENY/OBJ scores adjusted.
CUrrently, it has a 25 ENY.... and why??? Because HTC doesnt pay close enough attention after they get it in game with regards to ENY/OBJ scores. The IL-2 is a MUCH better aircraft than the 25 ENY. Nothing rips open gv's like it regardless of 23mm or 37mm.
The 2 biggest travesties in ENY scoring are the IL-2 and the Fw190A-8. The IL-2 would be better served with a 12 or 15 ENY (seriously, stop and think how devistating it is even with out ord), and the 190A-8 is a far better aircraft than a 31 ENY (the dual 30mm in the nose make it the best single engine "porker" and bomber hunter in the game).
