With the upcoming pet boost, I was trying to put together a tanky support magsorc for both Cyrodil and BGs. I've recently been playing a tanky magblade healer. High heals, good CC and very very tanky. Zero offense.

With the Magsorc I would like to be somewhat tanky, add CC plus actually have a bit of offense. Was thinking S/B front bar and Fire resto back bar. Not sure if a single pet or two. The three sets I was considering were

Cyrodil Crest - Really like the heals it gives
Impregnable - If I use light armor the crit resist is nice
Armor Master - I don't know if having hardened ward makes Dampen redundant.

Monster - Leaning towards Chokethorn. Not sure if I will need more healing or should use something offensive like Skoria
