hi!
From my experience, it works great! because I, like you, am still learning the game and trying to make it to end game content. You just check all the boxes that you want in a party like "slow & easy" or "newcomers welcome" and in the message box I usually write things like "need to clear for storyline progression!"

I got a lot of nice and exp. ppl join in and help, and some new players and some of which are also leveling alt classes which I don't mind at all. I form all my parties through PF now.

Give it a shot, you like it way better than douchebag finder.
