I hope that kill cams have a hard limit on them. 10 seconds is the longest they should last for. Will be all too easy too exploit if they go on longer than that. Teams could just refuse to spawn in if its a tight game.
The Reach spawn timer annoyed me at times, because I sometimes didnt change loadout in time, but ultimately it was better for gameplay that they did that. I just hope players cant spend an age in the customization menu/ deathcam screen instead of respawning.
Seems pretty straightforward, but games like Battlefield have gone the other way and its slightly nonsensical that they did.
