So here is V5 (ignore the text at the bottom, will change if you guys like this idea).
Win #3 is a huge bonus so that resources are somewhat the same as now for the first 3 wins. After 3 wins, you earn a small amount up until 10 wins. After 10 wins, you continue to earn a super small resource bonus per win.
This allows the casual player who likes the current 3 win system to still earn the same loot at 3 wins.
It allows the competitive player to continue playing for a further 7 wins earning some nice loot.
And then for the hardcore players - they can continue on even after 10 wins for a small trickle.
