What I'd like would be a sort of bar chart. Say, you're killed by a Vayne, and a Janna gets an assist. The "Killer/Assist" bar at the top with the champion name and icon would be the same, but there would be three vertical bars, one each for true, physical and magic damage received from said champion. The bars would be divided by ability. So, Vayne's "true damage" bar would just show "basic attack" (or, even better "Silver Bolts"), and her "physical damage" bar would show, say, "basic attack", "Tumble", "Condemn" and "Blade of the Ruined King". For any skills that applied CC, it'd say that you received CC - eg. "Condemn - X damage. Stun." "Howling Gale - Y damage. Knocked airborne." and "Zephyr - Z damage. 28% slow."
