Huh? Pin 2 ?

Hopefully that was a typo. Pin 2 is part of the voltage correction feedback circuit. The circuit will not function correctly with pin 2 cut.

That's strange about everything running hot at low Vcore too. I don't think cutting pin 16 would affect the overall power levels (heat levels) very much. Cutting pin 2 sure would though.
