Well maybe our tastes are diferents but I found that in GWX very well balanced the level of difficult in game. Much better then the first "The Grey Wolves" mod. I'm now in my WaW patrol in the end of 1943 and the airplanes are real nightmare
as was in that historicaly time and exactly I read in "Iron Coffins" for example. Only I may suggest you to try Rubini's great mod "Stay Alert Crew fix mod" which much improve the sensors in game and also to use a realistic way to escape the DD, some of that is perfect written in GWX manual v.1.03. Also maybe the good solution is to GWX dev team release GWX hardcore version (for experienced players, with longer repair times and more deadlier aircraft...) and other GWX light version (for player who like the much easier game), but there is a lot of work probably for that, the team not have a time for that or don't like that idea.
