After the removal of the previous spawn protection system (which was better but admittedly more buggy) that was removed, going back to the old system is still obnoxious where people show no sign of whether or not they can take 4+ pipes or several backstabs before dying.
A suggestion is to make spawn protection either a sizeable amount of overheal, which would protect them but not give them temporary godmode, and show particle effects to help as well. The second suggestion is to try to make a system similar to the last one but use particles or icons, rather than transparency or model colors, to show when they have spawn protec.
Not gonna make a vote on this since I just want to see people's thoughts and ideas.
