Low level MRD, have a few questions

[peaches]

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.

While what you say is true to an extent, for tanks it hardly seems to apply. As a Paladin, you can't use Riot Blade instead of Savage Blade to get enmity, despite the fact that Riot Blade has a higher combo potency. Either we don't have enough DPS for our DPS to hold enmity, or the actual DPS class abilities have hidden enmity values that our non enmity abilities don't.

I just use Fracture purely for the extra damage, and because I know two Overpowers is enough to get the Maim buff, and hit everyone with Fracture before I need to start working on Enmity again.
