Low level MRD, have a few questions

[SpookyGhost]

Fracture is terrible at holding hate as it doesn't have a threat modifier. It exists to do damage, not increase threat.

Damage is threat. It doesn't need a threat modifier when you are trying to hold hate on multiple mobs but need to focus on one. That's why this is true at low levels, but not true at high levels. At high levels you have an infinite amount of threat to work with - this isn't the case at low levels. You also won't see many people AOEing at low levels (literally just BLM blizzard 2 and that is just a bad BLM), so you won't need to cycle your hate combo through all the mobs... especially when it's just HS - > SS.
