"Raging Spirits" Summon More Than Intended

The 5 summon per cast limit "Raging Spirit" has does not work on the skill "Fireball". I have the support gem "Scattershot" that gives +2 projectile, I have the support gem "Unleash" which casts "Fireball" 3 times. I also have a 50% chance to cast "spells" with 2 extra projectiles. When all the buffs apply at once, I get 15 "Fireball" Projectiles, which all split into 8 creating 120 secondary "Fireball" Projectiles. Every one of 120 of these projectiles try to spawn a single raging spirit totaling 120 Raging Spirits. 110 of them die due to the 10 spirit limit the skill has, however the 120 spirits spawn at once causes intense network lag between the player and the server. The Latency jumps above 100ms.
