I'm playing all time on Hardcore

I am Hierophant with stone golem and 3auras ( enfeeble, vitality, arctic armour) +20 area from Devotion   

I have 6l with 4 red two green (culling 20Q = +10% attack speed, 38% dmg, on 10% kill) + one protector (20 atck. sp.) = +30

Taktics: 

1) molten shell (16s/943armour)  

2) 1protector (instead it is possible vaal haste and 3 ancestral warchief)

3) 2ancestral 

4) phase run - (39)% mov. speed, (30)% more  melee phys. dmg, 80% reduced Visibility to Enemies

also I can chills any boss, enemies walk through him (arctic aura)

5) vaal grace

1-6) enduring cry (but no need it)

CWDT tempest shield + molten shell, duration (I dont like IC for many reason)

PS: also possible is 4 totems with Great Old One'S Ward shield (1 protector+3ancestral) 

Since I've made some kind of the same build I have some questions. Occasionally I wanted to test out abyssus and lightning coil and sixlinked it before I had a chance to try out some other chests. It's ok on low and mid tier maps, but is it gonna save my ass on guardians since I've taken the berserker points. Or it's more profitable to get belly and more damaging rings and amulet. With all my buffs I have 200k dps. Is it too low for survivabilyty on high tier maps?

Please excuse my bad English :)
