Let us see who is in a PF group before we join it

[Viridiana]

If we let it get to the point of excluding certain players based on whether we like them or not then who's to say there won't be people requesting to see another players gear, their dps, or exact ilvl before entering df?

You already can see their ilvl before entering PF, and I'd almost be okay with being able to see their gear. You do realize that this thread is about PF, not DF, right? If you run into someone you don't like in DF, sure, just leave the group (or maybe kick them). For the PF, though, it's more of a hassle.

why can't you blacklist them or just leave the duty? It seems like a simple answer to your simple problem.

Blacklisting them doesn't keep you from joining a PF group with them, last I checked. As for just dropping group, not only is that an additional hassle on the person joining and leaving the group, but additional work for the person listing the PF, too.
