That's what I was saying, you have to go to parallel 12/2 downstream UNLESS you put GFCI in each outlet. An example that I actually have: A 12/3 run that has a series of 6 square boxes on it. The first, third and fifth boxes have a GFCI outlet with a second conventional outlet wired through the GCFI, all hooked to the "red" phase. The "black" phase is just wired through these boxes. the second, fourth and sixth boxes have the same setup except wired to the "black" phase. As a result, I ran about 100 ft of 12/3 instead of 200 ft of 12/2 but used 6 GFCI outlets instead of 2. A big deal? No but that's the way I did it.
i know what your saying. ive seen people run a 12/3 to a kitchen (1st box) then split off to 2 separate 12/2 runs. one run to box 2,4,6 & 8. The other 12/2 to 3,5,&7. this gives alternate circuits, but only 2 gfci's.
price wise...not sure which is cheaper. Personally, i try to locate a sub-panel in most of my houses close to a kitchen (i wire large 3500 - 8,000 SF horses mostly). the kitchen has most home runs of anything in house. ultimately this saves money.
