Echo of the elements is much more common than
Bottomless Depths. It provides many players with a nice quality of life buff, as having additional charges of abilities makes it less important to watch cooldowns like a hawk. In reality,
Echo of the elements isn’t taken because of any of that, it is taken because it provides us with more tools to spot heal with.
Echo of the elements allows you to effectively use your single target healing spells and reduces the amount of them do not feature a
Tidal Wave buff. It is great for fights like the Corporeal Realm of Desolate host, where the damage on the raid is low, but single targets will require attention.
