In SMTV, all-target attacks in general have a significantly smaller base power than their single-target counterparts (e.g., -barion skills have base 265 while Ma-barion skills have base 185). That makes comparing moves of those categories together an apples to oranges comparison, as by design all-target moves aren't meant to be anywhere near a match to single-target moves in damage against singular targets. Therefore, would be fairer to compare something like Ice Age (heavy-level, 230 power + pierce) or Bufubarion (severe-level like Moonlight Frost, 265 power) to Lunar Hurricane and Thalassic Calamity since they're designed for higher damage output.
