I'm all for a TDM but honestly I doubt they would do that. The real question is do they know how to do respawn modes. They haven't made a respawn mode since GR Future Soldier. The current structure for respawning after death have you go to loading screen window that takes several seconds. So I doubt they have the knowledge and doubt they put the effort. Which is why I play Rogue Company. Its free and it have 1 life mode, respawn mode, and more. The handling is good and the characters are unique like an actual class base.
I doubt Breakpoint will make anymore updates to ghost war. They didn't mention ghost war in the roadmap for the next 4 months. You pretty much going to play what you have. Ghost War is the most boring ghost recon mode I play. I like it but for it to not have some type of objective respawn mode makes it repetitive. The mechanics are bad enough, server, engine, bullet registration, and more. All hope went down the drain. Waste of 6 months suggesting things that never got considered. End of rant. Good luck on yall request.
