Obviously with one respawn spawncamping won't be an issue. With unlimited respawns, both teams should always have about the same number of people; even if one or two guys get back there they are going to run into plenty of opposition. With three respawns, however, spawncamping seems to become far more likely. Let's say a few guys on team A use up all their respawns early in the round. Now team B has a numerical advantage and this often lets them push the remaining guys on A all the way back to the team A spawn. Anybody on A who has played a bit more cautiously and still has respawns remaining gets the living daylights beat out of them by the entire team B the moment they spawn.
Any thoughts? Or better yet, anyone willing to switch the respawns on their server so I don't lose my last two lives each round by spawning into a hail of incendiary grenades? I understand that the guys on my team who rush like there's free food at the other end of the map might prefer that I'm swiftly dispatched so we can get the next round started; but that wouldn't even be an issue with the other respawn systems.
