my gld and mrd and only 19 and 26 respectively so my opinion might have traces of ignorance, but using fracture = not being able to use the enmity rotation, when every other member of the party, by virtue of them just doing their stuff (healing, hitting), are piling more and more hate... when i look at the hate bar at the party window, i could see other members' enmity increasing steadily everytime im not churning our my fb > sb... so i probably wont use fracture unless im absolutely sure i can spare a few rotations of non-enmity generation skills without losing hate
