What interests me about them are that you can play them solo (Yay solo content!) or with a small group or a really large group (no specific numbers given yet).
They're separate from raids and PVP.
So... are these their version of "instanced dungeons"?
I'm curious, as I'm probably going to end up being casual-solo, and being given solo dungeons is a VERY cool option for me!

What say you all?
