My two cents?... This system would't be to reliable due to the fact most people who are gonna be in range of doom will probably be armor changing blinking so the names as well as their icons would just disappear with them... by the time they reappear 2 seconds left...

(Although I do wonder why so many personal attacks... I think replacing the icon with a zz or a skull indicating a status effect would be nice, cute, and quirky. )
