Yeah, as of right now there are no options for HM Ops. The reason for that is most likely because there is no "gear check" for the group finder at the moment, and you don't want some new 50 in you're group with crap gear for a HM Ops. Things would go really wrong, really quick.
Well, there are plenty of undergeared 50's joining in HM FP's right now, so I know what you are saying completely.
