there are a lot of sound effects for spells that are not classic.

levitate had the crunchy "summoning" sound effect before the sound at the end.

all fire based druid nukes after firestrike had a different sound effect than the current one, which is the same as all of the lower level nukes.

manastone played the end of the levitate sound effect.

invis, gate etc all had the first half of the sound effect similar to sow, with the last part being the see invis buzzing noise.

is a lot more but this is just off the top of my head, im sure most dont care however in pvp this is a bigger issue than blue servers as an intelligent player was generally able to decipher what an enemy was casting based on the sound of the spell.
