I agree.
There's this, however: if there are greater rewards for the top teams, a lot more teams will be eager to fight for top spots, meaning more spending, more salaries, less tanking etc.
I'm not saying this will 100% be the case, everywhere. All I'm saying is that in a sophisticated pseudo-economy like BB changes will almost always have side effects which are not easy to anticipate.
BBB: 2 (S37 S38); Top tier: 7 (S35 S36 S37 S38 S39 S41 S63); Cup: 9 (S25 S35 S36 S37 S38 S39 S40 S41 S61)
