"Demanding" is an odd word to use for "allowing." "Condorcet" doesn't 
really refer to ballot form, though it is often assumed to use a 
full-ranking ballot. In any case, a ballot that allows full ranking, 
if it allows equal ranking and this causes an empty space to open up 
for each equal ranking, is a ratings ballot, in fact. It's Borda 
count converted to Range by having fixed ranks that assume equal 
preference strength. Then the voter assigns the candidates to the 
ranks. It is simply set-wise ranking, but the voter may simply rank 
any way the voter pleases, and full ranking is a reasonable option, 
just as is bullet voting or intermediate options, as fits the opinion 
of the voter.
