Strange. I remember Dragonrend faceplantning dragons.
TV tropes put it best.
"JOOR ZAH FRUL!" Basically the shout which drives down a dragon. Not only can you get those nasty lizards down - them faceplanting being an option - but each time you use it, you're introducing them to the notion of their own mortality. Which kinda makes you the dragon equivalent of the Grim Reaper. Bonus point if you're using Volendrung and punctuating each of your blows with "JOOR!" (mortal) to keep the dragon from taking off or roasting you: here, you're not just introducing him to the notion of death, you're literally beating sense into him, one bash at a time."
Additionally it is a good Shout to disrupt dragons own Shouts.
Hey, OP. In the future make sure you actually know what you are talking about when posting a complaint.
Too many topics around here is basically Skyrim svcks because X isn't in the game!
And then it turns out X is in the game, only they hadn't experienced it yet.
Ooops!
So, dragons can crash land when you use it on them.
