"How'd I die?" AoEs/ground effects from enemies and how GGG can help it.

I have said "How'd I die?!" Today more than any game ever.
Issues: AoEs/ground effects from enemies and aren't always visible - I'm partially color blind but when I die I rewatch the death and 8/10 can't see what's actually killing me or where it came from, or no enemies are around/already dead and i somehow die. I even send the clip to friends and they can't see anything under me/around me either.
Ways to fix it - add a variation of color choices for ground effects and AoEs (for enemies aoe, and your allies if you want to go above and beyond) being able to adjust what color and the brightness would make this 100x better. I really like this game in EA but if idk/can't see what's killing me, I can't get better.

Same for me, specially after killing an elite I died many times without know why. This is frustrating when you attempt endgame maps.
