Dragonriding

 Today, sorting through the vast number of things to do when you hit max level (or, in fact, just finishing the main quest campaign, which I did at level 68) I decided to try getting all the Dragonriding Glyphs. It turns out it's not all that difficult. There are a couple in Azure Span whose locations are not super obvious (Riverfork Crossing is not, as you might imagine, at a place where a river forks).

But I think I've now gotten the hang of dragonflying - especially once you've got the glyphs to invest heavily in it. The key is to maintain momentum - you want the buff that you get when you go very fast, with blue energy around your mount's wings. There are skills that cause you to regenerate Vigor (the resource that you spend on movement abilities) when you have this buff, meaning you don't have to land to regenerate it. What I've realized is that ultimately, you want to build up to this buff early on, and then you'll have enough speed to keep boosting yourself up (and thus get more momentum on your way down) or giving yourself a speed boost.

Now, I can actually climb more or less indefinitely if I'm careful - the bottom tier of the dragonriding skills causes the Thrill of Flight buff (or whatever it's called) to regenerate a vigor every 5 seconds - fast enough that you will be able to stay aloft pretty easily.

Blizzard has thoughtfully made this skill acquisition account-wide. You only have to find these glyphs once, and you get all the skills from the campaign quests (that reward the four mounts, which are also account-wide) on all your characters, so you should be able to take to the skies with aplomb the moment you come ashore.

It's a ton of fun, and I hope we'll see more mount customization over the course of the expansion.
