The Kyrian one looks quite underwhelming with mastery being a very weak stat for both havoc and vengeance, while the fury generation effect seems anecdotale.
The Necrolord one seems quite strong however, providing both good aoe, single target and defense. With that and necrolord being the best defensive covenant it’s probably going to make it the go to for vengeance.
The Night Fae I kinda have mixed feelings on. It seems solid in aoe so NF is likely going to stay a competitive choice in m+, however the single target seems lackluster as you will only be able to get one charge of the buff in those situations. NF has been the go to covenant for havoc in pvp since the start of SL and it’s most likely going to stay the same, however the legendary will have little impact on arenas as you will struggle to get more than one charge of the buff in that setting. Still it could be used to get a massive unbound chaos fel rush in bgs by striking a bunch of packed ennemy with the hunt first, so it has cheese potential.
The venthyr one has the most potential in my mind. It is very good in single target but also good in aoe, as meta still spreads sinful brand and eye beam/fel devastation will refresh it on multiple targets. Comboed with the blind fury and cycle of hatred talents and the conduit reducing the cd of sinful brand and the dot will reach a very high uptime. This might make venthyr the go to covenant for havoc in raids. It might even gave NF finally some competition in pvp, at the condition that blizz finally makes brand undispellable, by giving havoc options to play in a melee cleave composition rather than in a set up heavy one like paired with a mage.
