Illusions of life bug? I hope
It’s as designed. http://wiki.guildwars2.com/wiki/Illusion_of_Life
This skills gets a downed player up instantly for 15 seconds. After that they are downed again. To prevent being downed again one should use the 15 seconds to kill a foe.
So the damage showing is just what was needed to make it work as intended (to get you down again).
So a kind and friendly mesmer has given you 15 more seconds to play and fight
Arise, ye farmers of all nations
Arise, opressed of Tyria!
Arise, opressed of Tyria!
