Rotation
There is not a set rotation for vMA.
Staying Alive:
Be sure to keep your Matriarch active to heal you and sometimes to take aggro on the smaller enemies, Power Surge up at all times for the constant self heals, Use Hardened Ward frequently to keep your shields up and even spam it if you have to. Activete your Matriarch's 2nd ability when you need an instant burst heal in an emergency.

Dealing Damage:
Use Liquid Lightning and Blockade of Storms for the majority of your damage, Heavy Attack often to keep up your magicka. Use Crushing Shock for a ranged interrupt on enemies that are channeling an attack. Use Crystal Shards to do massive burst damage, but only when it procs from using other abilities. You don't want to channel Crystal Shards, it takes too long.
