Hello friend, I like your shot at a solo PvP build but there's some stuff I don't like so much:

- pets are pretty bad for solo, open world PvP. Your only burst heal is tied to the matriarch. Run restoration staff on your back bar and solt Healing Ward. It's Bueno

- if you INSIST on bringing pets to Cyrodiil, you need to run 5 X Necropotence to maximize their benefit.

- if you're playing solo, you need to prioritize magicka regen and max magicka. Rework your gear with these priorities in mind.

- bound aegis is bad and you should feel bad (jks, but it's not good enough to justify 2 slots)

- too much health for sure and maybe stam for you. Swap your food for Witchmothers Potent Brew and use Max Magicka enchantments on all your gear

- your only sources of CC are Atronach and streak for a duel wield mag sorc, you'll need Rune Cage. Remember to cast V. Curse, then Rune Cage, then Crystal Frags to maximize your Frags and Curse damage while they are cc'd.

Hope this helps!
