[Protective spirit][Shield of absorption][Spell Breaker][Ancester's Visage][Sympathetic Visage][Balthazar spirit][Blessed Aura][free slot]
For the free slot i recomend symbol of wrath, that is usefull to break body blocks

Now for the method:
Enter the city portal coming from gate of anguish;
Precast enchants;
Wait for energy to regen;
Open the door;
Watch the location of the mobs and enter the range of a Quickening Zephyr without agroing;
Cast spellbreaker and the prot stuff;
Run like crazy until u gather agro;
Remember to cast visage once in a while to prevent margonite warriors to knock u down with magehunter smash;
Keep in mind that when u need to recast Spellbreaker u need to go in the range of a QZ;
After you are happy with agro, pull them all in the same direction in a way that makes all CASTERS // Ranged attackers ball up.
After they are balled up, move close to them.
Make a cycle of Visages in a way that there is never a time where u dont have at least one visage on you.
Watch the fireworks

note: Recast the prot skills like crazy so you get healed (by the divine favor) to counter the degen from burning.
Have fun.
