So it's either talk to a dude to get a recap or read a book? : /
I miss when Anet presented almost all the story through the class/living story content with only supplementary info coming elsewhere. Or am I misremembering, because I remember that's how the latter part of S1 and pretty much all of S2 was and IMO that's how the core story should be delivered.
Because I sure as shit don't remember anything blood stone related in the main HoT story questline, unless it was early on and I've forgotten since last year.
