*Sigh* Repost as my first post was removed.
I cannot vote as none of the options align perfectly with how I feel. I would have liked to have seen an "other" option.
I loved the necro before and after the changes. We can run as tanks, healers and DPS and fill some niche roles. I enjoy necro in PvE and PvP. Scribing improved my love of necros with the addition of soul magic, enabling me to run a more Elder Scrolls necromancer, playing with soul gems. 12/10 would explode a skeleton again.
I have to say that I liked almost all of the changes to the Necromancer skills that were in U43, along with the Corpseburster set. Those things combined really made me enjoy playing with my Necromancer again for a while.
That said, I do feel that the class could use some more improvements. Grave Lord’s Sacrifice is pretty bad, the DPS the Skeletal Mage deals is underwhelming, Blighted Blastbones could benefit from the modifier Stalking Blastbones had (so that it at least deals more damage when it just stands there for a while before attacking your enemy), the new Ghostly Embrace could've been better (I would've liked the effects of the three patches to be additive) and so forth.
The class is in the best place it's been in years and it's still fighting to not to be last place in pvp. So they're moving in the right direction, but they aren't there yet.
GLS is the worst skill change in this game's history. The U43 changes were all good most of them have been requested by players for years. My favorite was the change to Ghostly Embrace it was an amazing surprise only for it to become useless in pvp the following patch. Many cc skills have damage (streak, talons, chain, eruption, javelin, charge, cripple, flail) but we have to be cautious of giving Necro a cc with damage.
Corpseburster is probably the most fun and thematic the class has felt since they killed the unique class identity of Harmony and Graverobber shame it's on a set, but if you play Necromancer in ESO you take what you can get.
Skeletal minion needs a damage boost, GLS needs to go away, tethers shouldn't break on los, execute scaling needs to be put on Scythe or Skulls, the class needs an instant hard cc no delays, and Skull needs to be undodgable.
For passives I'd change Last Gasp, and Rapid Rot completely. Last Gasp is just underwhelming they can add a unique buff or debuff to the class to replace it. I wish it wasn't so, but Necro fails at being a DoT class and Rapid Rot would feel more at home on a dk. My hopes for a reasonable sticky DoT on Necro are gone so change it to increase AoE damage by 15% or increase your damage and healing done by 2% for each corpse in the area up to 20%. For Death Gleaning and Undead Confederate I'd alter them. I'd have your minions dying count towards Death Gleaning as well to give it use in boss fights and pvp. For Undead Confederate I'd alter it to 150 health, mag, and stam recovery per active minion. Rewarding those that lean fully into the class kit with 450 recovery while most builds will still benefit with 300 recovery.
That's what I would change for my idea of balance, but if sorc with Hardened Ward and Streak is considered balanced by ZOS standards then Necro needs a lot more than this to become a balanced class.
