You need to complete T5 before you can enter T6-9 and then complete T9 before you can enter T10+. If you can't make a static look for learning groups in PF for the ones I mentioned above. Once you've learned all or most of the mechanics look for clear groups that don't require the win or say farm.
It took me about 5 DFs attempts to complete Turn 5. In nearly every attempt, the group stuck it out for nearly an hour before calling it. One attempt (with one wipe) on Turn 6. haven't tried anything beyond that, yet, though.
