We've all seen it before: It's overtime and the losing team is perfectly staggered: A player respawns, makes a mad rush for the crystal, guards, dies and is replaced by the next player. They have almost no hope of turning things around, but they succeed in wasting everyone's time for a minute or more. This is what you call a "lame duck situation".
Just a second or two extra on the respawn could disrupt the conga line of failure enough to end the game and save everyone some time and frustration. Perhaps a flat +2 or +3 seconds when overtime starts, or +2 on death instead of +1.
