Appropriate times to use Clemency?

[Galactimus]

Clemency is also an excellent way to get snap aggro on mobs that have spawned far away or in different corners of the room. Note: This only works on mobs who spawn on the Enemy List as "aggro'd" (basically anything that spawns as "reinforcements" while you are already fighting.) Clemency is also great for getting snap aggro on mobs that haven't appeared on screen yet, but are already aggrod on the enemy list. (IE. Brute Justice Robots as they fall from the sky but are untargetable for like 5 seconds.)

Basically, any situation in which your Healer is getting initial aggro because a Regen was ticking on someone, you can use Clemency to snap aggro all the mobs to you instead. It's like using a Flash that hits the entire room no matter where you are. This is going to become even more useful now that Clemency will be affected by the new changes to Tank Stance enmity generation.
