Shadow sin Alluvion vs holy fire badge

[AxeNoob]

why is holy fire considered better than alluvion?

with around 200 ping i can do maybe 12 hearthstub in 6 sec... 

why alluvion is 10 sec reduction every 10 sec ..

can any 1 help me understand?

because you can get legendary bracelet(Divine dragon) which increase your RMB(heart stab) speed by like double? Alluvion on the other hand can be very good also if you get the Tiger bracelet this gives you another something like 350% on dark strike and 900% on lightning rod. if you ask me Shadow assassin should have the Magnum(blue) soul badge and Skyrift which gives you 20% crit damage and  recovers 20% focus on dark strikes

holy fire gives you 30 sec on blue buff
