Gem reward in Masters & Champion leagues

The incentive to go to Masters and Champions isn't as strong as it could be. Getting stars by not sniping you earn gems.

After 10 points, they get one gem.

Masters 3: 2 stars 1 points
Masters 2: 2 stars, 2 points
Masters 1: 2 stars, 3 points


How about someone who gets 3 stars in Masters 3 for a raid gets 3 point towards a gem. After 10 points, they get one gem.
Masters 2, they do 3 stars they get 4 points towards a gem. After 10 points, they get one gem
Masters 1, they do 3 stars they get 5 points towards a gem, after 10 points they get one gem.

Champions, 1 star a base, get 5 points
Champions, 2 star a base, get 10 points
Champions, 3 star a base, get 15 points

10 points= 1 gem. This would be an incentive to not troll the lower leagues.
