Topic: The Z Buster

Saber spam works for me.

You're using Ground Dash on him, aren't you?  Attacking Sigma with something else doesn't knock him down nearly so often.  With the Z-Buster, or X's Overdrive, he's dead in seconds, and any damage you take is minimal.  I've done both a zillion times on Xtreme mode.

Been too long since I played to say for sure.

Saber+dash+turbo button works for Siggy. Works for any boss (short of Nightmare Mother and Gate) actually.

Get equipped with actual attacks instead of physics exploits.

Its an attack in my book.

Really, killing the second form in two saber slashes might also be seen as an exploit as attacks normally don't ignore the damage shield like it wasn't there.

*shrug*
probably

Indeed.  It's just taking advantage of the fact that the X-series generally doesn't apply selective damage barriers the way that Inti does in Z2 onwards, and using dash to reset your combo.
