I don't do SR in duty finder. I set the pace, I pull 1 group at a time. I may do faster runs if I'm running with all FC since we know how each other plays, but speed runs are not required in DF.

I haven't done WP since the Update. I farmed the shit out of it a while back for my Darklight Shield and know the pulls very well and how to run it so I'm not rushed (let the first Stalker pass you by pulling the birds to the far corner of the room).

If you're just starting on 50 content, I would do WP at least until you get your DL shield from Tonberry King.
