I am not so sure about that - I would still be intrested in using the RF to be matched up with other people who have cleared the content already. And let me explain why: PF-Farm parties require a certain commitment. It is ofc expected that you're staying for several runs or that you stay even after you've got what you were looking for - and thats fair, a farm-party cant be a farm-party when they have to look for new people after every kill.
RF is only asking me to commit to one run at a time. If I have half an hour on my hand, thats not enought to join a farm-party - it is however enough to get one, maybe two kills in RF! Using the queue instead of the partyfinder is not only more convenient, its also giving you more control over how long you want to go on, without screwing other people over.
