Hi guys! I was trying to make some fun builds with subclassing, It was a bit of a struggle because the system needs some improvements.
I like my rotations to be SUPER easy and for my class to still be my class, so that's what i was going for here. I would love feedback and ideas for improvements while keeping things easy.
I would also love if others can share some builds that are easy to use.

Thief Mundus. Equipment i am using 5 Ansuul's Torment body + 5 Deadly weapons. This can be replaced with 5 body whorl of depths + pillar of nirn/order's wrath weapons for magicka. If there's better easy to use options let me know. They are stamina builds but you can always swap morphs etc and make them work with magicka.

2 arcanist builds

First build is PlagueNist Aedric spear + grave lord + herald of time
I added some necromancer to arcanist while keeping arcanist still a strong theme. (not sure if necro class mastery is needed)
cp biting aura, master at arms, thaumaturge, fighting finese/flex - weapons is dual wield frontbar - backbar anything but i recommend destro staff or bow
Equipment Velothi Ur-Mage + Velidreth/flex
rotation is backbar 1>2>3>4>5 > frontbar 1>2>3>4>5>4>5 barswap repeat. (can also try 4>4 > 5>5)



Second build is HellFireNist ardent flame + aedric spear + herald of time
I added dragon knight to arcanist.
cp biting aura, master at arms, thaumaturge, fighting finese/flex - weapons is anything frontbar - backbar anything but i recommend destro staff or bow
Equipment Velothi Ur-Mage + Zaan or Velidreth/flex
rotation is backbar 1>2>3>4>5 > frontbar 1>2>3>4>5>4>5 barswap repeat. (can also try 4>4 > 5>5)



Now we move to 3 necromancer builds i did and i have to say i love the warden bear with glowy eyes, it works so well with necromancer.

First build is LightNatureReaper Aedric spear + Grave lord + Animal companions
Given the skill styles that were given for free, plus the fact i love the glowing eyes bear. i decided to add jabs + warden to necromancer
cp Deadly aim, biting aura/master at arms, thaumaturge, fighting finese/flex - weapons is dual wield frontbar - backbar destro staff or bow
Equipment velothi ur-mage/ harponer's wading kilt / mora's whispers + Nerien'eth (given we can use poison injection on this build, we can replace mythic or monster set with Master bow)
rotation is backbar 1>2>3>4>5 > frontbar 1>2>3>4>55555555 barswap repeat.


Second build is UnderworldNatureReaper Daedric summoning + grave lord + animal companions
i decided to add sorcerer + warden to necromancer so i can have 2 pets - I can try a version with the flying bird lady is people want.
cp Deadly aim, master at arms, thaumaturge, fighting finese/flex - weapons is dual wield frontbar - backbar any but i recommend destro staff or bow
Equipment harponer's wading kilt / mora's whispers + kjalnar nightmare / Selene/flex
rotation is backbar 1>2>3>4>5 > frontbar 1>2>3>44444444 barswap repeat.


Last build is InfernalNatureReaper ardent flame + animal companions + gravelord
i decided to add dragon knight + warden to necromancer
cp Deadly aim, master at arms, thaumaturge, fighting finese/flex - weapons is dual wield frontbar - backbar any but i recommend destro staff or bow
Equipment harponer's wading kilt / mora's whispers + selene /zaan/flex
rotation is backbar 1>2>3>4>5 > frontbar 1>2>3>4>55555555 barswap repeat.


And that's it. I'm not sure if class mastery for necromancer is better than lingering torment, i'll let you guys decide.

I can try making a build if someone has requests.
