Frustration with Purple Orb-Emitting Plants

I've had enough of those plants that emit purple orbs. You instantly die if the orbs explode near you—what's the point of these plants? There are too many things happening on the screen when you're surrounded by mobs, and you can't even see the orbs coming. On top of that, the orbs move way too fast. Whoever came up with this idea must be ''a genius''. Just delete them or improve them somehow—make the orbs emit slower and more visible when you're surrounded by mobs. Period
