Can we please disable Raging Spirit spawns if we are at the cap?

I cast a fireball using wildshards that multi casts and then forks.

It creates 6x8x3x3 projectiles (Very cool). But it also spawns 432 fire raging spirits. I'm getting lag spikes every time I fireball in an enclosed space.

If I turn off raging spirits then there is no lag. But they are what's applying my fire exposure and giving me culling.
