The reason you wont find many groups for this is because the content is not "spam until you get a drop"

When content requires you to do it ad-nauseum to get your reward the player base benefits from everyone knowing how to do it. I remember when my group first started getting CC 5chest runs and nobody else was, if a few members werent online we couldnt do any more, no 5 chests for anyone! then as strats became readily available and we began to teach more people how to do it, it was much more beneficial to everyone!

With Darnus Hard - 1 win - Fight done - no need to do it again unless to help people. So unless your LS is going to have you in their main group, or is willing to help their members through, you wont find people doing it.

People seem to think 2.0 having a solid token system will help the dungeons. more than likely, an LS that knows how to beat the content will get their tokens and have no reason to go back, whilst the rest of the player base struggles to get a clear.

No need to spam it, no need to teach it.
