DHR, then why is Bullet Punch a VGM? It's only used in OU on Scizor because of STAB and Technician. Same circumstances for Breloom with Low Sweep. That just doesn't seem like a valid counteragument. Provide a different reason Low Sweep isn't a VGM and I'll go along.
And now seeing it's not there, yeah Bug Bite should be a VGM too.
