HG spawn in Rathe Mountains should work the same way the cylopses do

[douglas1999]

In Rathe Mountains hill giants did not ever spawn in predictable static positions. They worked the same way cyclopses in rathe work; there are a bunch of trash wandering PH's some of whom will sometimes respawn as a cyclopse. So sometimes you can find a whole field full of cyclopse and sometimes there aren't any up.

I'm just confused why the HG spawns don't work this way, considering they are in the same zone and almost everyone seems to remember them working this way.
