Some planes are flown because of ENY restriction, some because old hand's like their odd plane, and some because the challenge of flying a high-ENY plane VS the uber-planes.
I do not agree with Bozon on the La-5 and Fw190A5 hangar queen issue, what they cannot do is to force the enemy to fight due slower max speed - the faster enemy can choose to fight or not.
If you normally fly the A8, the A5 feels cheating good, if you don't want to molest bombers that is, and the A5 K/D confirms that.
The only way to solve the disparity is to
perk the pilot.
For Bozon, this means - No Hispano's in his Mossie, and only one engine working
just read the rest of your post--wow man, are you a gv'er? all the planes you have listed here are flown everyday, and by more than 1 person.
all of these planes are 2nd line favorites to most pilots. just wow, where have you been?
