Developer PurpleFooz released a Dev Diary on the forums that helps to answer a few questions about update 22. He briefly discusses the story line and mosters. He also talks about what he calls airship monsters.
From the looks of the early test footage (which can be seen below) we will be fighting airships and their crews.
He doesn’t talk about this at all, this is just an idea on my part but seeing as guilds have airships and the pirates do too, I wonder if airship to airship combat could be included. Guild ship vs. pirate ship or possibly a new PvP type arena where guilds are the crews of their airships and it could be guild vs. guild…
Later in the forum post he answers some specific questions that came up. He talks about the treasure and how it will be tiered up via difficulty, I suspect similar to quests newer then Menace of the Underdark. I think the loot will look similar to the current heroic 3BC loot which was added a few updates ago, but epic of course. I do hope they add new stuff though. He also says they are going to revisit the Heroic XP and possibly add a new saga with 3BC and the Sentinels of Stormreach series. Once they get them fixed of course.
My favorite thing is how this won’t be just a rehash of old content. With a new quest added for epic content only and 3BC getting a new public area and facelift I think this will breathe some new life into a quest pack that I’ve always loved but never felt the need to play.
