I strongly disagree that mess is a bad thing in sport. Open circuit is way more fair and interesting than close circuit. When money and partnerships matter too much, we get BLAST's clown fiestas where all the same teams playing against each other again and again no matter how bad they become. If we no longer had stories like Outsiders or GamerLegion, there would be no reason to watch CS anymore.
Same in football, although it's luckily formally not a closed circuit yet (but rich are trying!), when it became impossible for teams like Steaua and Red Star to win Champions League anymore and every year it's Real, Barcelona, Bayern or one of the top English teams it became useless, no one to cheer for. The only way close circuit works fine is when it designed like in NA sport leagues, with draft and salary cap, so it's still worse than open circuit, there are no true cinderella stories anymore, but at least there is a constant rotation of contenders. Without that closed circuit is always bad and favors rich rather than smart or talented.
