When the difference in team points is great, increase damage for the losing team.

0-99: No changes

100-399: Increased damage for the losing team, increased points earned for the winning team, changes are proportionate to the point gap

By having no changes when the point gap is not significant, the winning team will be the same as it would have been without these changes.

The winning team would receive increased points for kills because they're fighting a tougher enemy, so getting kills indicates a higher skill level. This ensures that the final points reflect skill level differences.
