Specific damage types should have their own unique sound effects
This gif raised a small discussion in a private server.
It gave me and some others the idea of sound effects specific to every type of damage, rather than just spikes getting one. On top of just being a neat touch, this would likely promote players getting a specific type of shield to protect from those elements, such as for example getting an Attraction Shield in THZ2 after hearing an electric damage sound from those flashing floors. It could also possibly promote mappers to remember to use a specific type of elemental damage somewhere rather than accidentally putting Damage on there.
