Armored Saint is definitely traditional classic metal as opposed to US power metal. I'm with Sanitarium78 here, if Armored Saint is on this list, Dio should be too. US power metal I'd consider to be like Jag Panzer, Iced Earth, Manowar, Brocas Helm etc.
Also this list is invalid if you don't hit Into Battle by Brocas Helm very, very soon.
Brocas Helm/Hatchet/Exmortus/Midnight Chaser 11/22
High on Fire/Kvelertak 12/12
Exodus/Nails/Hellfire (???) 12/20
Neurosis/Bl'ast!/YOB (???) 12/29
