I've cleared them all in less than 6 hours, then went to farm v 2.0 3.0 and 4.0 through DF. Chances to farm and succeed 4.0 in DF is very slim at this time. There was this brand new party, one of the healer asked if there's anything he need to know. I said "I've cleared it through DF blindly, so will you. If we wipe, we wipe and progress through mistakes." He then started spouting how elitist I am and pray for a video guide tomorrow...
