The skill Deafening Roar is bugged. It is not applying the Major Fracture Debuff to elite or higher mobs, or players immune to CC.
The description reads:
"Roar with bloodlust to terrify up to 6 nearby enemies, fearing them for 3.3 seconds AND applying Major Fracture to them, reducing their Physical Resistance by 5280 for 7 seconds."
The key word there is AND. Fear is a debuff. Fracture is another debuff. This literally states "applies debuff X AND applies debuff Y", but it does not. It seems the fracture debuff is tied to the "fear" debuff and CC immunity, but it should not be.
For proof this is not simply a tooltip bug, consider the Nightblade skill morph Surprise Attack:
"Slash an enemy, dealing XXX Physical Damage and afflicting them with Major Fracture, which reduces their Physical Resistance by 5280 for 15 seconds. Attacking with Surprise Attack while Sneaking or invisible stuns the enemy and sets them Off Balance for 4 seconds."
The keyword there is AND. Off Balance is a debuff, stun is another debuff. "applies debuff X AND applies debuff Y". If an enemy is immune to CC, THEY ARE STILL AFFLICTED WITH THE OTHER DEBUFFS and set off balance with Fracture applied. Just because an opponent is CC immune, does not mean they escape the Fracture, or Off Balance effect.
This is also not in line with ANY other skill that applies Major Fracture. Not a single skill that applies Major Fracture is conditional upon CC immunity or mob "Elite" status.
As a reminder, those are:
Dragonknight > Ardent Flame > Noxious Breath
Nightblade > Shadow > Surprise Attack
Nightblade > Assassination > Mark Target
One-Handed and Shield > Puncture
Warden > Green Balance > Subterranean Assault
None of which have such requisites.

CP is a crutch for people who can’t sustain and want to be "tanky" so they aren’t immediately punished for making mistakes.
