If you want to make enemies, try to change something.
If the timer goes away as soon as they move, then, yeah, I don't see a problem with it. Talking should also make the timer go away, so, like Kilgore said, they can't just insult and run to exit.Also, mercs should only attack after this timer goes away, to prevent the spawn crash, let the player have a chance to react, etc.
I am in favor of a timer after spawning.That way I have time to run up on people and set off my bomb, and they can't shoot me as I approach them.

Here's a thought, how far away from the exit grid do players spawn? Is it possible people could line up between the spawn and the exit grid, so even if you don't move you're fucked?
Yes, I'd like to see this return too. Just makes sense.
