Oh. I must have read your question wrong. Here is a better answer based off of your new post: The video clip to which you are refering is a solar grenade augmented by Radiance to inflict a one-shot. The reason the grenade counter does not go down is because of another Sunsinger ability that allows the user to carry two grenades. Radiance [b]does[/b] buff melee, but the way you were describing did not sound (to me) like the sort of question you thought you were asking. Sunsinger, while it can help teammates more then voidwalker, is not a very support oriented class. Rather, it is a individual support. Think of it as all of the potions in traditional MMO's/RPG's shoved straight down your throat at once. If you want all knowledge on the abilities, click the link. Radiance is my favorite focus (might change once I try them all in-game). You have the potential to jump into a fight, slam two grenades straight into the heart of the enemy, shoot some noobs up, die, revive yourself, one shot the remaining guys after they are shocked you returned, and win the fight. All while looking like a boss!
