11 is a step backwards, I would concur, in this regard. Bloated PDFs have caused me no end of grief with remote print houses, that now demand sheet-by-sheet files from us, or reduced/optimized (in Acrobat pro/preview) work.
We isolated some culprit fills - like the hexagonal insulation hatch, and some others that were making pageloads painfully slow.
There needs to be better resolution options on OS X, flattenning, and built-in filesize optimization. Just compare a set of DWF's - amazing at 1/4 to 1/10th the size, same information.
