As someone who does not PVP at all, and runs HM FPs from Group Finder daily, I think this is a great idea. I've seen many players instantly decline the FP group finder, and have come to realize that most of this is due to them being in a WZ. And if you are having to wait a long time for a PVE group finder, you may want to look at the reason why (ignore list?). On my dps I usually only have to wait between 5 and 15 minutes.
The difference is you are running HM FPs with other level 50s. There are lots of those popping all the time. Wraiven is complaining about 10-49 leveling content...normal FPs, planet heroics, etc.
