I decided i didnt like having to farm up for bfury so i decided to do arcanes for my mana, bottle for the hp, and maelstrom for aoe. the deso is an add on after that when my w is doing well.
it allows me to just be so much more functional quicker than bfury and i clear lanes plenty fast
For early just go standard mid ember, even if you're safelane.

Double Battlefury is CORE on ember, unless you are building single target. In which you get a desolator/1 or 2 daedalus'.

If you ever go late enough to get a rapier, save or sell one of your furies.
