I play as a sunsinger and I've noticed a major issue with the revive perk. Really, there is no point having it in high level strikes and missions because the high level enemies destroy you the instant you get back up again. I was thinking that you could add in an over shield for a few seconds while reviving to allow players to escape from danger or to catch an enemy unawares. tl:dr : the sunsinger needs a shield while reviving and a bit after to be able to escape. Please feel free to respond Edit 1: Xelon99 came up with another alternative: a sort of eruption to push all enemies back so you have time to gather your bearings/run/commence murder
