Ice bite support to trinity support :
when we have...
1) high elemental dps claw(no more rely on ice bite support)
2) our damage is balance enough to gain "Resonance" from trinity (it basically when we use wrath)

herald of ice to wrath
when we have...
1) "% increased mana reservation efficiency of skill" on helmet implicit(eater of world)
2) "% increased mana reservation efficiency of skill" on helmet suffix(essence of loathing)

OFFENSIVE QUICK SUMMARY
maybe you still don't understand why this build is still over power , will once again quickly explain it.

-molten strike itself already very powerful vs single target
all we need to do is stack up projectiles number

-molten strike have no attack speed penalty(many melee have)

-molten strike have added fire damage on the gems

-molten strike projectiles deal 50% less damage
(just simply calculation)
let's say we deal 100 damage -50% = 50
50 x 4 projectiles damage = 200 (still x2 dps and x4 with nimis ring)
let's say we stack up our projectiles number to 8 
50 x 8 projectiles damage = 400 (there are x4 dps and x8 with nimis ring)

I think this is the main reason why this skill is very powerful
