Scale rewards based on contribution similar to a FATE and base it on their job so people cannot just run around the map or endlessly just attack ice and sprint past everything else.

Some people are even just tapping a key on the shatter base points and claiming they are defending when they are really just watching youtube and claiming they were ganked when a lone enemy goes to bust them up.

The winner should get a bonus and it should be a significant XP bonus, like 1.5 more.
