Clown Fiestas: is there a better way?

In most team fights, it's hard to tell what just happened, what went wrong, and how things could have been different. It's often over in 2 seconds and seems to stem from a decision made in a tenth of a second. This problem affects casual players, but from an Esports enthusiast perspective, it's a problem that must be handled carefully. I don't think changing the overall pace of the game is an option. Games as slow-paced as Starcraft get boring, but games as fast-paced as CS:GO or your typical fighting game are just frustrating to follow. It's exciting when 1v1, 2v1, and 2v2 fights break out, but any more cooks in the kitchen, and it gets harder to decipher what's going on. These are my ideas on how to potentially fix it, but ultimately I'd like to know if anyone has different ideas.

What if there was a buffer between damage taken and health calculated? What if champions took reduced damage from multiple champions? Let's say that current health is calculated every 0.5 seconds. All damage taken during that 0.5 seconds is placed into a 5 unique variables, one for each enemy champion. If any one of those variables is higher than the champion's current health, the player dies instantly. At the end of every 0.5 seconds, the champion's health decreases by the amount of damage dealt by the two highest enemy champions. It would have to work differently for DoT and true damage, of course, but imagine the implications. Faker's LeBlanc still one-shots an ADC, but supports and tanks are contributing only to the nature of their role.

Then, what if there was a visual indicator of who damaged who? It's not unlike when a champion is slowed or stunned. Based on the order you've placed enemy champions in your information screen, a specific color or visual effect occurs over you when that champion has dealt the most damage in the last 2 seconds. Hell, maybe even use something like that little portrait Garen gets.

These are the simplest solutions to this kind of problem that I can think up. I don't pretend to know how difficult it might be to implement something like this, but I feel it's important enough to start a discussion. How can we end Clown Fiestas?
