The problem is, "seeding the DF with experience" will only lead to a similar experience that you have on PF.

I can assure you 100% from experience that the most successful parties on DF for this kind of endgame content are the ones that DON'T have people with experience. Those parties are the ones that people will stick through till they clear it.
Experienced people only want a quick clear, and WILL rage quit after 1 or 2 wipes, thus disbanding the group. If that's what SE is looking for, they are shooting themselves in the foot.
