I've noticed a lot of spells have had their SFX changed over the years. Balance Beetle, Bloodbat, Frost Beetle, Sandstorm, Centaur - the list goes on and on
I'm very nostalgic for the older SFX, and I would love to hear them back in some shape or form, even if under the 'Classic Mode' toggle.
Not sure if the old sounds are unusable or lost, but I love them and would love to hear them some time in the future :)
