Hiya,
This game desperately needs a killcam and while we're at it we should also increase the spawn timer and have it fixed at something like 30 seconds to make kills more rewarding and making objectives a bit less annoying. Currently, even if you manage to kill the enemy a lot and frequently they always seem to get back just in time to interrupt the objective on certain locations. A longer respawn timer would surely solve the issue of feeling like there is an endless amount of players coming your way.
Poll up on top just because it's fun to see actual feedback rather than unconstructive comments.
