I like these invasions, but man I wish there was more than just 2 areas.
I have my Vulpera's Make Camp set up in Vale for now. For other characters I just port to Jade Forest, then fly or take a FP and go afk for a minute.I really wish they would've left the Shrine portals instead of the Jade Forest ones.
Hardened Hive is unable to be completed for me, when I get there all of the hives are already on fire.
I've bound my Hearthstone to the Vale. From there I can go to Orgrimmar and from Org to both, Uldum and Zandalar. I don't like this but it is faster and less boring than Flight Paths.
