Coming from offline FFs, I was confused when I could use wind to kill wind elementals. My sister, who plays very few (offline) games, was confused when I could kill fire elementals with fire, and my dad, who plays only one game (the card game that comes with Windows), is definitely confused why elements doesn't matter. The excuse that an elemental wheel would be confusing seems just like saying "we didn't want to bother programming and balancing an elemental wheel so we'll blame it on newbies instead". Though pertaining to cosmetics, I agree that we need some more solid effects rather than nebulous glows.
