This is not only a weak argument, but an easily reversible one. This is a fantasy game, why can't my regular bullets deal as much as a big explosion. Why are you not in favour of more options if thats your stance, let people live out their fantasy better with an option to use other animations.
Just as an example to show why the argument is weak, if next patch zenos flew at the moon in his underwear and cut it in half, and saved the universe, why would that be a bad thing, This is a fantasy game - let it be fantastical.
