While it's a NICE ability, it's just NOT that powerful and it has a 6 minute recharge on it. Why doesn't the Fatesinger epic moment work on bosses? Every other big epic destiny whammy does, so why not this one? It's absurd.
Oh, and why doesn't it work with handwraps? It works with every other type of weapon as far as I can tell but, for some reason, not handwraps. (And don't give me that **** about how 'handwraps aren't a weapon--it says NOTHING about needing a weapon). Did it just never occur to anyone that a monk would ever run in Fatesinger? Kinda silly considering that Draconic Incarnation and Magister are absolute balls for melee toons and we gotta get our Arcane lives SOMEHOW.
Anyway, harrumph harrumph fix it harrumph. And change the "doesn't work on bosses" thing. Harrumph.
