It has it's potential.
It's just because it's generally awkward to use it, even with custom controls, it's aggrivating to use it properly/extensively. Some characters get 'slides' out of their jabs and downsmashes whilst walking, so pivot walking allowing a speed similar to running for some characters is definitely under appreciated.
But yeah... awkward plus looks silly... and I'd say it's the looking silly which throws people off attempting to explore it...
