Zombies Exclusive events in BO6 deserve to carry forward into BO7. It’s pointless grinding for exclusive emblems/rewards if they’re just going to disappear once everyone moves on. These events take effort and hours of runs. If they carried them forward, it’d show who actually put in the work instead of erasing the successes, and it would be a shame for these to be forgotten.
Other than bragging rights, it’s about keeping achievements meaningful. Treyarch should recognise the time players put into BO6 instead of pretending it never happened.
