Kyrian Covenant
Vesper Totem - Starting off on a strong note, this Covenant Ability is shaping up to be the strongest numerically (though numbers are very very much subject to change) at the moment and is smooth and simple to use. You can place it next to your foes, and move it to a new target (or to follow that tank that has an irrational fear of your
Terremotos) off the GCD once every 3 seconds. It will explode 6 times, 3 when you cast damaging spells & 3 when you cast healing spells within the 30 second duration.
Simple, thematic, and for the moment strong. It's everything we want in a totem!
Venthyr Covenant
Chain Harvest - At the moment this Covenant Ability is in dire need of numbers tuning as it's not even worth having on your bars whatsoever for Elemental (again, numbers quite subject to change.) This is
Catena di Fulmini &
Catena di Guarigione combined, does less damage and healing than either, and doesn't interact with
Maestria: Sovraccarico Elementale,
Fulmination, or
Seismic Thunder. It would be quite nice if this was made stronger, as the Venthyr Covenant ability that all classes receive -
Door of Shadows would fill a part of the very large hole left by Gust of Wind when it was removed at the start of BFA.
Necrolord Covenant
Primordial Wave - This Covenant Ability is quite interesting! For any scenario where you want several active
Folgore del Fuocos this will help ramp your multi-dotting up and throw a
Getto di Lava at each of your targets with
Folgore del Fuoco active for good measure. This is a widely applicable ability that is just as simple and flexible as Vesper Totem, but is the only one of the four Shaman-specific Covenant Abilities that makes you choose between the damage and healing provided whereas each of the others allows you to utilize both.
Night Fae Covenant
Fae Transfusion - A 3-second channel makes this undesirable for Elemental from the start as we don't need even more reasons to hold still for as long as possible, and the overlap that
Soulshape has with Ghost Wolf pushes us farther away from this particular covenant. As it stands it's on the weaker end of our Covenant Abilities, but as always numbers are subject to change.
