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.
Silver Edge: Can be a ganker now, if you really want. Before, he was a joke of a ganker. With an actual upgrade, he can be a ganker with more late game contribution to shut down certain heroes.
Moon Shard: DK is one of the best carriers of Moon Shard. He was tanky before and had low damage. He can buy this item with little risk because he rarely needs more armor, and more attack speed lets you keep enemies perma-slowed, and other Shard carriers would be much easier to kite usually, like Tiny, Alch, and OD.
Radiance: With the buff you get miss chance, meaning you can get it later and it'll still be effective, DK is a great Radiance carrier, especially since he's also a great manta carrier. If you get this after Hyperstone/SnY-BKB, it is a real menace to enemies.
Anyway, point is, I love DK this patch, just like you.
