The only feasible scenario would be driving through a puddle after a "LLLOOOONNNG" downhill canyon run. The thermal shock "could" warp of even crack your rotor regardless of slots, or X-drills, regardless of cost or quality. If you're warping/cracking your rotors from driving/autocrossing/tracking, buy some better rotors, and/or research the pad/rotor compatibility. A pad that generates and operates in temps of 800-1000 degrees, for obvious reasons can't be matched to a rotor designed to operated in the 500-700 degree temp range.

I have seen it happen to a few rotors and they havent been cheapies ether
yeah if you pay big dollars you wont have a problem but I cant see the merit in it it would have to make them weaker ,I know the V8 supercars over here use slotted rotors
it just my preference but I would never get X drilled rotors
