Appropriate times to use Clemency?

[Bright-Flower]

- To apply the effect of Divine Veil, when you see that the heal does not come.

- When you see your HP very low then you have 15 mobs on my face and the heal sleeps.

- When the heal is stupidly dead in an AoE and I have to keep the dps alive to finish the boss.

- When you want to troll a heal that makes you a whole speech, to tell you he finds it insulting to his healer status. (True)

Hmm, and in ShB they could all be isntant cast heals to boot every requiscat...
