"Players can be killed too quickly if there is an AFK killer or auto-killer on the map (ie: in many mg_ maps) and therefore, I made this modified version of the Player Respawn plugin in an attempt to mitigate this issue."

For setting times you could use this and create a cfg for each map (sm_auto_respawn_time), it may be a bit time consuming though
