Bug,
I more than anyone would like to see the CHOG made a perk plane, and feel its addition to the game was a mistake and blatant "look what we have that WB doesn't"-ism.
However, the CHOG WAS carrier based in combat..not land-based.
And while it wasn't in combat for very long, the 200 CHogs built were in intense combat around Okinawa for several months, with quite a few kills of Japanese AC.
