ScottyK,
No, the G4M1 was added by HTC primarily for scenario purposes. Nobody has ever suggested the G4M1 would be anything other than a hangar queen in the LWA.
You can find uses for it and it does have a nice attribute, very fast climb rate to about 12,000ft, but it always will be a hangar queen.
Some people seem to mistake the He111 for something other than a hangar queen in the LWA. Most people who advocate for it are quite well aware of how it will do in the LWA and just want it for scenarios, which is a perfectly reasonable thing. Some others seem to think it would be far better than it will be.
Additional Axis bombers that would be good in the MA:
Do217E
H8K2 'Emily'
He177A-5
Ju188A-1
P.108
P1Y1 Ginga 'Frances'
Axis bombers that would be hangar queens yet would be good additions:
He111
SM.79-II
