Anyone done Throngus on HC who can give me a few pointers.

the mace part is hard but i manage to survive it but when Phlanx hit me its nigh impossible.

The amount of healing needed to survive is crazy-

1 move from flames - ok this is doable np, heavy dps but ok,
2 twilight arrows is what kills me,

- i use a druid as a healer for my setup, efforecence (aoe heal), wild growth(aoe dot heal) with rejuv rolling on ppl
- paladin use Holy Radiance + Devine Guardian

using direct heals is kinda worthless since you have to move to avoid flames constantly

he is cakewalk on normal (ofc) but HC is driving me crazy, I thought 1st boss in Halls of origination was hard but after killing him i consider him peanuts in comparison.

my chars are all over 340+ in gear and i have np in other HC's

any pointers is welcome
