The only "PLng" I like, is DFB - because it lets me take a new concept to 14 or 16, and decide if I like it or not, without investing eight or so hours into it. (Hey, I play slowly when solo, sue me! :D )
Or, well, I'd've taken it back on Live, when my villain main ran out of content just shy of going to Grandville. Couldn't even get Paper missions. Wound up running the same "destroy Longbow base" in .... Siren's Bay, I think it was. Over, and over, and over, and over, and over, and over, and over ... gah. From level 39, to level 42. GODS that sucked arse. So I'd've taken a PL to get past that, for sure. If I'd been offered one. :)
