This is a build for SAP Tanking post Morrowind patch, I've spent a long time trying to make my old build viable since.
Basic stats: With correct rotation and CP 160 Tri Stat Food (this is based on Imperial my current race)
Health: 30k
H Recovery: 400
Magicka: 35k
M Recovery: 1.5k
Stamina: 25k
S Recovery: 800
Physical Resistance: 29k
Spell Resistance: 29K
Evasion Chance: 15%
Crit Resistance: 1k

DPS(Single Target): 10k
Spell Crit: 25%
Weapon Crit: 15%
Spell Damage: 1.5k
Weapon Damage: 1.5k

Please note I have not fully tested this build as I am not CP 660.

For PvP probably swap all infused with impen and probably use bloodspawn however I find that using Scourge does really help with survival.

This set provides a bit more damage, I find it seems to help me hold agro on the trash as an AoE of about 5k-6k damage really gets the attention of the trash mobs.

Abilities for PvP:
Reverberating Bash replaces Pierce Armor
Shielded Assault replaces Inner Rage
Mass Hysteria replaces Refreshing Path
