I was just in Hydatos instance for over 2 hours and ones kept killing mobs to spawn nm's there and only the lvl 50 one ever spawned. But said all the nm's was open in it. Not once did even Ovni spawn during those 2 hours. Please increase there spawn times or increase amount crystals each one drops. Getting 8 crystals in 2 hours when need 350 for just the weapon is way to low.
