So there have been lots of conversation about the Sunsinger subclass talent Fireborn that you can get. Confusion about if the talent works only for a single person or if it also benefits the team. Here is an example of what this talent in action looks like and may shed an idea of what it possibly might function like within the fireteam dynamic. I personally believe that it is a singularly affecting ability and will not also revive your team. That you will revive and will have to revive your fireteam manually if there isn't a restriction on revives. Fast forward to the 3:00 minute mark of. The video to see the talent in action. Let me know if you feel that it will be a fireteam wide affect or if it will be singular. *This video is to just show what it looks like when you activate the talent.
It's certainly an interesting ability. I've heard rumours that upon activating Radiance you will automatically revive downed allies when close enough. However there is no mention of reviving teammates in the skill tree anywhere, for Radiance or Fireborn. We'll just have to wait and see, the lack of any mention in the skill tree makes it unlikely, but I think it would be a great ability to give a bit more of a supportive role to SunSinger. Right now all it does is buff cool downs for allies nearby, with the relevant upgrade that is. So without a revive capability, SunSinger isn't really support IMO. Only Defender for the Titan is. If this is the case, I think that's kinda lacking on Bungie's part. Why would you stunt a clearly support-inspired subclass with no actual supportive qualities?
