I'm so disgusted by this game

What's happening in ranked is precisely what SBMM will cause in casual too; if you match predators against just diamond, diamonds will simply stop playing.

If you drive away diamond-tier, the burden of playing against predators then falls upon platinum. Repeat.

It's a classic runaway cascade failure scenario, and it's going to cause the death of Apex.

The only solution I believe in, is no match making; that way the burden of the predator population is spread amongst the entire population of the game.

Another less desirable approach would be to reduce the effect of the high skill ceiling weapons, abilities & combat mechanics, and increase the impact of luck dependent aspects.
