Yep, agreed.

But Matt said "i have a bunch of streams in the frequency domain and wanted to 
independently manipulate their pitch without having to go back into time domain 
for each". I was guessing that meant he wanted to pitch-shift the streams 
individually, perhaps by different amounts, without changing the frame 
alignments for the individual streams, so they could be summed in the frequency 
domain and fed into a single IFFT/overlap/add at the end.
