The Lost Shores release will kick off with an event this Friday. The content looks interesting, especially the endless dungeon. I'm not sure how I feel about the new armor -- some people on the official forums are angry that it appears to be the first step of the genre's typical loot-grind treadmill. I think I need to see how it's implemented, but that is a concern.
I'm still thoroughly enjoying the game, though. I missed most of the October event, so I'm really looking forward to this one.
