Dedication to Hardcore Mode
Once you play Hardcore playlists in Call of Duty it opens your eyes to a completely new style of play. It's fast-paced and incredibly fun. It's also not a mode that gets a lot of attention from developers and often only includes limited game modes.
With Call of Duty: WWII we saw Hardcore players only get a few modes to play at first. After a long wait the developers added in some other options.
It would be great to see Treyarch deliver better support for HC modes in Call of Duty: Black Ops 4. This means launching with a decent amount of modes, including Kill Confirmed.
This also means supporting the Hardcore players through each of the DLC with a dedicated hardcore playlist with the new maps and quick integration.
