Here's the deal. You're 23 points away from promotion. You win. You get 197 points. However, only 23 of those actually matter. The rest are fully wasted.
You now have to play a promotion match still to get to next tier. Sounds fair enough, does it not?
Yet, what if you lose it? Well then you don't go to previous 977/1000, of course not, if you lose you lose 190-200 points, so you get to 800-810/1000.
Let's say you lose a full 200 points. Now you're 800/1000. You win the next game, but due to one player being lower ranking you only get 198 points. Now you're 998/1000. Your next game, even if won, will be only for 2 ranking points. That's bullshit because in this case by winning 2 games with similarly ranked people you'd only get 200 points and still be able to lose all of that in a single loss. 2 wins = 1 loss in this case.
But let's see the demotion part as well, shall we? You have 25/1000 points at... Gold 5 let's say. You lose your game and lose 200 points. OR WAIT! Actually you only lose 25 points since the other 175 don't matter whatsoever. But nevertheless, you get to your demotion match, and win it. You get 200 points, you're now 200/1000. So by losing 1 game and winning one game with similar ranked players, you actually win 175 points.
But wait, there's more! In a perfect world, you're only matched with similarly ranked people, but then... you also get people doing their placement matches in your teams. How are these given to the teams? No clue, but from what I saw it's a total randomness as you can get amazing players or players that are so bad it's unbelievable, so it makes you wonder if these placement matches people are given based on their previous ranks or just a random die roll.
Overall, I think the tier promotions/demotions favour the people close to losing their tier and defavour the people trying to gain a tier. And I don't like that.
What do you think?
