People have this myth that you have to afk farm (YOU FARM HEROES) 3 battlefuries and that you won't do any noticeable damage until you get 2-3. That's just plain wrong, you will still do a shit ton of damage with 1 battlefury, probably the same amount if not more as 1 deso (and you get extra farming power and hp/mana regen), it's just that when you pick up that second bfury you can just feel your power jump exponentially as you start to 1 shot supports and creep waves.
I can see the deso build being fine in certain situations, especially with how cloud9 plays as a team and how sing plays ember specifically. He basically plays a 3 position ember, he just sets up kills as an intiator with chains + sleight and gives up all the farm to EE and his off-laner. In that case the deso build is fine, he just wants to get a quick -7 armor for his carries and has no intention of carrying into the late-game (he's got 2 other players for that).
However, if you're playing a 1 position ember or even a 2 at times, I think the battlefury build is way way way superior. One battlefury gives you comparable damage to one deso (when I say comparable, I really mean MORE), more sustainability (all the regen), and more farming potential (1 shotting creep waves). What's not to like? I'll tell you what, the fact that you are still squishy as hell and will die in the duration of a stun, but that's just ember the hero and the deso build ends up with this same achilles heel.
Anyhow I promised myself I wouldn't get roped back into this debate, and I did, FUCK YOU BO!
