Breathe Fire.1. It has a terrible name, on par with
Slardar's skill names.2. It gives him a nice nuke for farming in-lane and early fights.
3. It got a buff where it applies a damage reduction.
4. it..wait what?
YEAH. This baby now applies a 20% damage reduction at lvl 1, scaling to a 35% at lvl 4. Try last hitting when that debuff is on you! It's not gonna happen! This one addition to the skill turns
Dragon Knight from a middling midlaner into a BEAST. Doesn't matter who it is, if you have a quelling blade and use breathe fire on them, you're gonna have last hits for days...or at least 8 seconds.You thought
Breathe Fire fell off a lot later in the game? Think again! Combined with your armor, if you use this on some pesky right clicker you're hardly even gonna feel them hitting you. Remember it's percentage based so the later the game goes, it remains just as relevant, unlike 
Enfeeble.I mean this is a huuuuuge buff for my buddy DK, and it's not the only buff he got!
He got corrosive breath to be fatal, towers have less armor so he can push better, and he got an item
Silver Edge that gives him everything he wants(other than BKB).I've always thought that a fed DK is one of the scariest heroes to go up against lategame, and now he has another weapon in his arsenal. This patch has changed DK from a niche pick into a powerhouse, and I love it.
Anyway, point is, I love DK this patch, just like you.
