It says in the Army Pilot Training Manual for the C-47 not to three point it; rather, to make transport landings ("wheelers") with the tail erect or in a tail-low attitude. Same with the DC-2 incidentally.
IIRC it says it's hard to judge the flare in such a big aircraft and the landing gear damages easily if you stall in too high.
EDIT: Here we go. Got it slightly wrong. Regarding the C-47:
"You can make a 3-point landing in a C-47 airplane, but this type of landing is not advisable. Reason: Weight of the airplane causes undue strain if you happen to drop in. Normally, make a tail-low landing."
Regarding the DC-2 (this is from the Douglas Operations Manual):
"A normal approach and landing should be made under partial power reducing power as you come over the fence. Landing should be made on main gear, dropping the tail as the rolling speed decreases. By making a wheel landing of this type, better control of the airplane, and a smoother landing will be accomplished."
