So I don't know about anyone else, but when an ally dies, and I intend to rezz them, I actually have a hard time picking out where they are. Ground combat can be so busy, that picking out the one body on the ground that is your defeated ally can be very difficult.
I propose a very simple solution (simple in concept, I can't speak to the programming).
When an ally is defeated, make the border of their name white instead of black, and make the actual font a bright red that is impossible to miss. Likewise, have this bright red slowly pulse from lighter to darker, which may help the colorblind.
This would make finding a defeated ally very simple, as their name and thus their location would stick out like a sore thumb, which is exactly what you need in that kind of situation.
