We need more placement game

TL;DR : The title says it all, 10 placement game isn't enough. Placement game are much more "liquid" and less static than going through LP and promo, and bad streak, as well as good streak happens where you are carried and/or trolled by teammate. 10 game isn't enough to capture that picture

So if we go by "OP champ" standard, the win ratio varies between 45 and 55% win rate between "OP and UP champ" If we go by the "elo hell" standard, there is one troll in every game, since it's not you there is 4/9 chance he is in your team and a 5/9 chance he is in the ennemy team, so again it's something like 45 vs 55%.

A good argument could thus be made that if you have skill superior to your league/MMR you could carry and win 55% of your game. For the sake of argument, let's DOUBLE this differential and say it is 40-60

What it means is that no matter how great you played, you will still loose 40% of your game, and no matter how bad you play you will still be carried by your team in 40% of your game.

So, there is a 5,48% probability that someone will win 7 or more of his 10 placement game just by being carried by teammates. Alternatively there is this same 5,48% chance that he will win 3 or less. So There is 11% chance that someone has absolutely nothing to do where he is. That's one person in every single game.

If you just double the number of placement game to 20, that same 70% winrate by being carried or 70% loosrate by being trolled drops to 0,65%, that's almost 10 time less. (keep in mind that if we go with 45-55 you can pretty much double every thing i just said)

So, if you double the number of placement game, you divide by 10 the number of people "misplaced" Ok... but why not just let them climb where they belong ? sure u could, and they will !!.... eventually. But the whole point is that is much easier to move up and down the ladder during placement. Once you have been placed there is some stickiness to it.

First you must reach 100LP (or 0) and once again in order to get there you will loose 40% of your game, so basically if you gain 20 LP per win and loose the same amount when loosing, after 10 game you have a net gain of 40 (6 x 20 - 4 x 20), and you have to gain 100. Then there is the matter of the promotion (ok, i read it was going to be changed in some way but i didn't dig into it too much). There again, since you loose (or win) 40% of your game for nor reason of your own, there is a 35% chance that you loose (or win) two or more of your 3 promo game. That's a lot !

And again i went with 40-60 and there is good chance that 45-55 would be a better assumption, the number would be even more staggering.

So, i understand that some people might find it annoying to have to go through 20 placement game instead of 10, but what's 10 more game compared to the number of game it takes to right the wrongs.
