If you have the same succes on PF than on DF, you are doing it wrong on PF.

It takes a bit of practice, but usually you can see wich partys are going to suceed and wich ones are not. Most decent partys on PF can clear and farm any content prior 2.2 and Levi ex, except maybe T5...
Of course, now there's not farming partys for primals Ex, cause there's not use on it, but you can easilly find a party to clear it once if needed...

For exemple, I woudn't join "Titan EX FARMING NO RAGE QUIT" or "Levi Ex" description "Everyone is welcome but some experience woud be great". At least not if I want to clear the instances...


But if you join the right partys, PF has a great success rate.
