You have probably noticed by now that ArenaNet likes to be a bit cryptic with its Guild Wars 2 teasers. Case in point: a Ventari teaser image posted on Twitter yesterday with a tiny bit of lore text. What does that mean? Who knows!
Presumably the game’s staff know; they’re just not telling us yet. That’s the definition of cryptic.
Fan speculation has run between another Elite Specialization to a new Ventari legendary for the Revenant. Of course, it could just as easily be that Ventari’s come back from the dead somehow; it would fit with the same amount of information presented. Cryptic teases are just that. Enjoy speculating in the comments!
