TL;DR All dragonflying vigor should be restored upon mining/skinning/herbing with the cultivation talent, otherwise farming with dragonflying mounts is just frustrating.
Sure, for the first 10 or so nodes, dragonflying is a significantly faster way to farm nodes. Especially with the talent not to have to dismount for herbers and miners. But after that, the original flying will begin to catch up. All that landing and steering to the node eventually depletes even the best flyers’ vigor (I have all the isles advanced courses finished and I pride myself on being good at steering when farming, friends gave me similar feedback).
This leaves us with standing on the ground, writing a frustrated forum post, waiting for the damn vigor to replenish.
@Developers: Give one good reason why we shouldn’t get all our vigor back upon looting a node. Otherwise, just give us all our vigor back…
On a fun rating: This is almost as fun as watching a multibox druid steal all your nodes in the previous expansions.
