Why keep DF off of new content?

[hagare]

Doing difficult content through Duty Finder is far, far more likely to make a non-raider go "This is a terrible experience, I want to stay as far away from this as possible" than "Wow, this is great, I want to do more of this!"

depends on the person really.
you can't just paint everyone in the same color.
and even if they go like that, at least they have the choice to do so.
difficulty of content should not affect content being in DF.

and what about raiders that prefer to do it in DF?
