Funny you rant about this without even knowing a main point. Radiant skin is bugged. When in sun singer special damage is halved and while using radiant skin damage is also halved. Using the song of flame is a waste also because for one, does nothing to the warlock, two will maybe let everyone else get one extra grenade out. Not that big of a deal. Learn some details before starting this bs. Just because self res isn't useful in a main part of a new raid doesn't give people the right to bash it.
