Sound Issues
This is a long-standing issue that has been pointed out repeatedly, not just recently. The developers have also frequently acknowledged this problem, so it's likely a difficult one to solve. For this challenge to be resolved, users will need to be patient and cooperate with the developers.

I largely agree. I also think the death screen should be simpler and more standardized.
Reviving and Item Pickup
I completely agree with you on this. The delay when reviving teammates and picking up items is particularly stressful. This is the issue I most strongly want to see improved based on this article.
