Change Leviathan Mechanics to Reduce Sabotage and Conflict

Currently it is possible for any strong player to sabotage the rewards of others during a leviathan fight. This has led to a lot of conflict, namecalling, and stress. Please change the mechanics of how leviathans are destroyed. A good solution to this problem would

1) Reduce the ability of players to sabotage the rewards of others. In order for this to be the case, leviathan rewards should on average have similar total value no matter how they are destroyed.
2) Create no additional incentive for players to control the behavior of others beyond what already exists.
3) Be simple enough that the solution can be implemented in a reasonable amount of time.

Further discussion of this problem and ideas for potential solutions are being suggested in this thread: https://goldfire.me/forums/thread/5f614aae1f0790236bb71921/to-the-fast-killer-of-the-levi
