Probably already been mentioned before, but I wanted to throw my thoughts in.

For guilds that don't want to have hundreds of members this an awesome thing. I led my current guild in WoW and did 25 man and 10 man content. Came to rift and decided we would rather do 10 mans.

Not saying do it how wow did it, and I know the cronicals are a way to keep people in the story but I just thought i'd throw this one out there.

Gear could be the same item level or perhaps lower.
