I don't see the reason for adding it before other planes. I think other planes would be used more... both in scenarios and in the MA. Did it serve in every theater? Ya, it did, but so did the PBY Catalina (and there have got to be others). Being able to fill a void is, at least in my opinion, more important than serving in all theaters.
What would it really be used for? Low level attacks on shipping seems to be the most common response after reading this thread. This leads to the question of who is going to attack ships at low level?
In the MA's it's suicide unless the CV is undefended or you're fighting the barges. If someone wants to hunt down and attack derelict CV groups or AI controlled barges, I guess that's fine, I just see the population of players wanting to do that as very small. I guess it would be useful to take down towns in the EW arena.
In scenarios (granted, I haven't flown in a lot of scenarios), I don't see it getting much use either. Will it get 6 pilots per frame? 8? What convoys is it going to attack? Will it be used to attack CV groups? Will it attack ground targets? It's not going to be used as a nightfighter. Is it expected to survive when doing just over 300 mph on the deck?
I'm not saying not to add it, it definitely should be added. I just don't see why we need another twin-engined (early war) allied attack aircraft more than other planes. I still think German bombers, and Japanese and Russian planes of all types should be given priority until we have a more well-rounded selection of planes in the hangar.
Just my $0.02.
