From my perspective, the same thing was true of slicing swords through armor, raising allied morale, casting spells, praying for divine intervention, avoiding diseases in the swamp, etc. None of those simulated activities bore any meaningful relationship to the real thing they ostensibly simulated.

Like Melf's Minute Meteors doing fire damage. Those things are still supercooled by the time they hit the ground. Those trolls should be fine! (Until you use Melf's Acid Arrow).
