Raging Spirits + Wildshards = RIP

I'm currently running a combination of raging spirits + Wildshards on my fireball.
I also have 2x cast from unleash

whenever the wildshards procs, hundreds of raging spirits skulls are rendered and the game lags to the point where you die because of it
The raging shards are capped at 10, so the many that get spawned automatically vanish because of the cap.. this should be suppressed visual and performance wise

Same problem, raging spirits combo with wildshards on fireball just tanks FPS. No matter how low I set graphics settings etc, it will tank FPS. As OP said, a LOT of skulls are clearly being rendered. They exist for what seems like a fraction of a second, but the FPS drops last until they are all gone.
