Spell Balance Suggestions

[Detective100]

I can't say Sound is the most anti-melee tree in the game, myself.

All Sound has that can keep melee users at bay, is cascade (which is a difficult skill shot to land against a capable opponent that doesn't move in a predictable pattern, at least without set up)
Sound strike, which is a homing slow move that works like blood bomb or shard shot (Can miss if they walk out of range).

Sound relapse... Maybe? It heals, but it won't stop someone from still bursting you down inside of it. The confusion effect only happens at the last tick.

On the other hand, sound has abilities that rely on short ranges, where melee users can excel (or at least, trade well) against.
Cacphone requires to keep distance.
Sound burst is a close ranged damaging moves that slows.
And Sound's E, while it gives +10% dr, also pulls enemies in during it. You pull an enemy with ifrit, you are in for a bad time.

Wind overall, has better anti-melee abilities.
