I'll believe it when I see it as we have been promised many other new features over the years that were never delivered. _*cough* Guild v. Guild *cough* Alliances *cough*_
There's also the chance that they lock it behind a paywall like they did with build templates and equipment slots (though I hope they won't do that considering how _that_ went over). Considering the amount of time that goes into making legendary weapons and (especially) armor, I'm personally hoping it will be like the zenith skins where I can just open my hero tab and pull out the gear I want, equip, select stats, slot runes/sigils and infusions and get back to the game. That would also allow for each character to have their own transmogs applied to each piece. It'd also eliminate my current grumbling about wasting the limited time I have after work moving everything through the bank every time I want to play a different character for a bit or trying to figure out who has Astralaria today! (Guardian, Warrior, Rev, Mes, Necro, Ranger)
I also ran into the issue where the map refreshed and I no longer got a text box when trying to interact with the vent. Edit: replayed the whole chapter and ran into the bug where I dropped the grenade in spite of selecting the option to refuse to drop the grenade... Nothing like having to replay the whole chapter just to be denied the choice you were going to make anyway, thanks Anet
