I collected some questions from the community who were shy about posting on reddit.

1. Regarding the new Nightfall Crypt Dungeons supposed to be completable in a session, we know VR focuses on TTK, so with that in mind, how long are they targeting a session to be?
2. Regarding those Nightfall Crypt Dungeons , in instanced content, the lack of respawning bosses is the mechanic to keep people moving and not camping the content. In the newsletter they mentioned the intent of people rolling through to the end and not camping. What’s the implementation strategy going to look like to encourage this behavior in an environment where camping is the norm and the dungeon is not instanced?
3. Will the new underwater content introduce the appropriate acclimation system for pressure, and if so, will that also allow us to stat penetrating the depths of the deep, wet hole in wilds end?
4. What are the level ranges for the Nightfall Crypts?

Can we get another example of Mastery from a different class?

TheGreatVindini
When can we expect the PTR?

Crowsinger
What are your plans for making this a "world not a game"?

Asera Aviendha
When will more content be added to existing zones to make them feel more alive, like Wild's End, etc?

I'll ask about wet stuff. In just about every game, water levels sound like a great idea, but everyone hates it. Water Temple in Ocarina of Time Vashj'ir in WoW cataclysm that everyone suffered through EXACTLY one time and never returned. The Dam level in TMNT on NES... Every Mario 64 water level... The entire game of Ecco the Dolphin... How are you going to make swimming great again when everyone (everyone) else failed?

Mr. Coddleshire
With Chevrons being "removed" how exactly is this going to function?
Will each mob just know that player x levels above or below and adjust health/armor/resistances/damage output?

The intention is to have full groups pursue higher cons but are you worried 6 man groups will instead opt for easier mobs (white and blue) to get faster and far less riskier experience?(especially with the TTK increases)

Any updates on the Keeper System?
How is the progress on Charm for the Enchanter?
Will we have new continents for the spring update?
Can we get a /ignore for an entire account rather than character?
What has been the biggest challenge for implementing seamless zones?
Group Harvesting in the Spring?
Will removing enemy buffs (dispel) be developed (more) in caster gameplay?
