Radiant Skin does not have the utility to go into a room full of sniper Vandals and Dregs on an arc burn Nightfall and res two over zealous members. In solo play it's even more resourceful. Fireborn users that are trying to play with death are bad, yes. Quit trying to generalize an entire spec because some people don't use it correctly. To be honest you could say the same thing about Defender Titans.
