I just finished the starting experience for dracthyr, and I'm not too thrilled with it. You don't get Soar from the get-go, and even then it still has that long 5-minute CD (even though this is technically the Dragon Isles) or any movement-increasing buffs at all during it, and some questing areas are rather far from the quest givers to just go on foot, so the back-and-forth, while not the majority of the starting zone experience, did bug me a little and brought me out of the experience for a moment or two.
At least in Legion, for the demon hunter starting experience, they gave you a mount early on to speed things up a little.
Also, when I was starting my dracthyr, there was a small bug in the quest that had you train the Fire Breath skill three times, it didn't show the optional objective to use the stones that would reset your Fire Breath CD, so I just kept waiting the 30-seconds every time.
The Soar ability is also a bit clunky, IMO. Like, if, while flying, you tilt upwards even by just one single degree above horizontal, you start losing speed quite fast. Too fast, IMO.
Also, unlike how it was with the original DK experience, you get absolutely
zero talent points to spend, even after you're told to finally choose a specialization mid-way through the starting experience. You're just
given abilities, and only after you finally reach Stormwind/Orgrimmar, you suddenly have all talent points according to your level available for you to spend. Minus the ones that were automatically spent to give you certain abilities, like your interrupt, that is on the third row of your class tree.
On the plus side, it's nice to be vindicated on a certain topic that I discussed with in the past with a "certain someone":
