Venthyr had a nerf in 9.2, which worsened the legendary Sinful Hysteria. The legendary is still strong, and Venthyr is still, in theory, the best spec for DPS as Balance. This is when we have access to 2 legendaries. NF is at the top when you have a tier set and only 1 legendary.
As Venthyr, you will gain a huge burst 20 + seconds into your cooldowns, you will lose out on the on-demand burst which Night Fae provides, but you will gain more overall damage, and if you plan your cooldowns well, you will be able to nuke down a priority target instantly.
Venthyr needs more thought process, and it is harder to play than Night Fae. Have in mind you will be able to swap between covenants. So be ready to play Venthyr and Night Fae. Night Fae is still a more versatile spec which provides more to the PvP and PvE scene than Venthyr.
Note that Venthyr needs more practice and more focus than Night Fae does. Always plan your cooldowns well, and don’t forget to do mechanics/use defensives if needed. :)
Night Fae is the go to covenant for raids if you want a more stable and chill boomie spec and solo play. It provides significant burst and single target DPS. It is also really good for situations where you need to burst something down in a short amount of time. However, one side effects with Convoke the Spirits is that you hit random targets within range of yourself.
The Night Fae covenant ability (Convoke the Spirits) casts 12 spells within a 3 second channel that you can cast while moving. 8 of these are damage spells and 4 heals (if ranged), on average. If you are in melee the 6 healing spells will most of the time be Rake and Thrash instead. So slightly more damage, but not enough to bother only using it in melee.
Soulbinds and Conduits
Night Fae: Niya
The Night Fae Soulbind for the best damage output is Niya.
Double legendary is going to be available. This is one covenant legendary + the one you want to pair it with. Here you will play Primordial Arcanic Pulsar with Covenant one.
Venthyr: Sinful Hysteria Each time Ravenous Frenzy is applied, its duration increases by 0.1 sec instead of 0.2 sec. Additionally, Ravenous Frenzy lingers and will not overcome you for 3 sec (instead of 5 sec) after it ends.
This is a fair nerf to venthyr in general, but venthyr is still good and will be played in some scenarios.

This is a fair nerf to venthyr in general, but venthyr is still good and will be played in some scenarios. This and some time before you want to use all your AP and spells that give you more AP.
Primordial Arcanic Pulsar for Night Fae
Primordial Arcanic Pulsar is a legendary that gives you 12 seconds of Celestial Alignment after you have spent 300 AP. This is the new Best in Slot legendary for Night Fae. This legendary puts NF to more of a 2 minute cooldown spec instead of 3 minutes. So you can use your Convoke the Spirits with Primordial Arcanic Pulsar proc
Tier set is coming back, and the Balance druid one is powerful, and will make Primordial Arcanic Pulsar a bis legendary no matter what covenant you are playing.
Tier set 2 piece: Entering Lunar Eclipse Creates a Fury of Elune at 25 % effectiveness that follows your current target for 8 sec.
Tier set 4 piece: While in an Eclipse, the cost of Starsurge and Starfall is reduced by 20 %.
These tier sets make Balance more mobile due to less cost and more Astral Power overall. It is a pleasure playing with it.
For Night Fae
As venthyr, I would play most of the same trinkets as you play with as Night Fae. When you play this covenant, try to have Scars of Fraternal Strife and Moonlit Prism, Shadowed Orb of Torment or Cabalist's Hymnal. Combinations can vary depending on if you are in a cabalist group or fight. All of the trinkets are good, but simming them is always a good idea.
