With the current system I don't like 24 hour HNMs unless there was maybe only one or two of them. Now when more areas come out and content I would be fine with having both, NMs like we got and maybe a handful of HNMs for the most dedicated LS. Only thing I don't like about the 24 HNM spawns is you end up with people using claiming bots and that takes no skill and makes an unfair advantage for others.
