Actually, the SBD-5 doesn't belong in early war setups either.
That said, the CTMs have to work with what they have and the SBD-5 and TBM-3 are both reasonable enough substitutes for their earlier counterparts.
I just wish we had matching oposing forces. A TBD and SBD-3 against a D3A1 and B5N2 or a SBD-5 and TBM-3 against a D4Y and B6N2.
