You're going to have to wait longer to get serious reviews on necromancer, but here's some of my thoughts.
1) Costs and benefits
A lot of Necromancer skills are nearly identical to existing weapon or other class skills, but have drawbacks (curse self / deal less damage) unless you consume corpses or use other skills. This doesn't make necro competitive.
2) summons being so late in the tree
Most people are going to stop playing their necromancer before they get to the fun part. My guys are getting close to 30 and i've yet to unlock ANY of the summonable minions besides blastbones, which is bugged and does no damage rn.
3) aesthetic and style
definitely the best part of the necromancer. I love the color and the magical effects that swirl around your character, the sound and visual designs are top notch. Especially the ultimates. Theres a few skills that are choppy; mainly, Life Beyond Death, when you use the skill on a corpse the giant rune circle just.. appears, in 1 fps. it's like an image flash, it doesn't feel very natural. The res ultimate is the same way. Other than that, 10/10 in this department.
4) Actual performance
We won't be knowing how necros truly fit into the meta for a few months, in particular i mean this for support roles (tank and healer). DPS have a hard measure number to look at though, and so far the verdict is : Stamina is strongest class in the game, magicka is weakest class in the game. Funny and sad. the conflict between mag and stam is so ... deep and conflicting and confusing. Stam skills are so few and far between - and necro did a great job of having lots of stam morphs don't get me wrong- but yet stam is always the strongest spec, yet magicka is always safer, but weaker, and it's just so muddled up. In particular, for a class like NECROMANCY, i would have hoped magicka would be the superior route, but I can't really complain because of how stam is already treated (look at stamsorc)
5) moment to moment gameplay
Fun. Summoning things, keeping corpses in mind, using powerful abilities, the large sweeping aoes and single targets are all very nice and well done. It's fun to play, and definitely fresh. It's also as a class 10000000000000000 lightyears past where the Warden was in terms of cohesiveness and thematic appropriateness. Wardens were like druid wanna bes but not really but kinda yes but also based on vvardenfell but have nothing to do with vvardenfell and... so on. Necromancers are just good. it makes sense, it fits the theme, every skill feels unholy and necromantic. It's good. The ultimates in particular are awesome, i love them all.
I could continue to delve into class design and problems with Zos's base system but i don't think that's really what you want comments for. So my
TL;DR: Necromancer is very fun on a visual and sound design level, and has some exciting and fresh new gameplay elements. The potential is high, but aside from stamina dps we're not sure if or how necros will fit into the meta.
PART 2: having gone back and read your post i severely misunderstood what you were asking for but i'm leaving this here in the hopes that it's still helpful information. Since you play solo and for fun; do it. It's very appealing in this category and will not disappoint you. Elsweyr the zone as well is absolutely jam packed full of beautiful scenery and quests that just make summerset and morrowind look like clowns getting in a clown car and driving off a cliff into a volcano because the lore and atmosphere is phenomenal. and that's not even mentioning the dragons, which are awe inspiring and super fun to work on as a community. Even if it's early to say it, Elsweyr is (and will 99% likely remain) my favorite chapter, and i'm very critical of this stuff. It's just SO good. and don't worry about the map size. it's WAYYYY bigger than it looks. it looks smaller than a standard base game zone on paper but it's easily a crap ton bigger.
My thoughts.
Doesn’t really feel like a necromancer to me. Sure there’s dead stuff but it’s missing the core feeling of a Necromancer. The pets aren’t really pets. They are just abilities disguised as pets. They are incredibly short and you have no permanent summons. They are as much of pet as the nightblades shade thing. This is a pretty common opinion I see being shared. 8-16 seconds ruins the pet feel it should have. Up it too a minute minimum eso..
Stamina is pretty strong and magicka is a hot mess. The diffrence of the two are terrible. I personally feel magicka concept if it needs some serious reworks as they are just worse stamina morphs.
Do I think the class is worth it? Yes
Did eso butcher the idea of what the necromancer could have been? Also yes.
Does the class need a lot of work and changes. Oh yes..
I give it a 6/10 as a class. It’s not terrible, but it feels like it fell short of what it means to be a necromancer and could have been executed a lot better.
It is the first class with animations that work well with normal animation canceling. Specifically bar swapping. The rotational interest skills are pretty nice. Always nice to not have poor magplar's nearly static rotation.
Too many skills are bugged to get a good feel for PvP.
I started a Bosmer stamina based Necromancer. Bosmer not so much for the racial sustain, but because he takes less falling damage in solo overland PvE. I am not so much into necro skills. My main goal is to have a well balanced and rounded stamina ranger with bow and dual wield and probably a werewolf morph just for questing, overland bosses and gathering and maybe a little bit PvP. Although i rather play healing Templar in Cyrodiil....
I dont like the visuals of Bone Armor. But Scythe is like DK's Burning Ambers a nice survival skill. There are a few nice stamina morphs and even an illegal skeletal Archer
So far the Necro is probably the stamina build i like most for solo gameplay. Combined with weapons skills he plays really like a ranger. But then, my goal is not really a necro.
The skills are just to DIE for
Sorry had too, even though i am yet to play the necromancer (as im a console Pleb) the animations and colour scheme of the skills draw me in a lot, especially the Expunge skills. Ive never been one to gravitate towards death classes but i am excited this time around.
Killing things with the Magicka necro is painfully slow. I'm going to convert to stamina tonight and see if it's any better.
