Of these options, I'd say the first is the lesser of two evils.
 * 1) If leaving a game reduces or nullifies ELO adjustments, it can be abused by purposefully having a teammate leave when a loss is expected.
 * 2) If leaving a game has no impact on ELO adjustments, it can be abused by trolls purposefully leaving a game to reduce the ELO of the other players on their team.
