Treyarch will be making tweaks to the revive time in the final game.
Call of Duty: Black Ops 4 recently had a beta for both its competitive multiplayer modes, as well as the new Blackout, and Treyarch made plenty of changes based on feedback from both. One of the issues that people often cited with the battle royale mod was that reviving was way too quick. While in games such as PlayerUnknown’s Battlegrounds and Fortnite, reviving a teammate takes quite long, doing so in Black Ops 4’s Blackout beta was much faster.
Apparently, based on that feedback, Treyarch are going to be making some tweaks to the same. YouTuber tejbz recently uploaded a video (which you can view below), in which they mentioned Black Ops 4 director David Vonderhaar revealed while speaking to them that Treyarch would be increasing the reviving time in the final version of Blackout. They will, in fact, be doubling it- hopefully that sorts out the issues people had with it during the beta.
