Hook based MMR concept

Introduction:

As you may or may not know, there was a Q&A yesterday, where Patrick (lead game designer), Peanits (community manager) and Justin (product manager), answered questions that were asked on twitter and on the forum by the community.

I want to specifically react to Patrick's claim that basing MMR on hook state as well as escape/kill could break the system and maybe put an 8h 0k in the win category.

And since i do nothing with my life had some free time, i tryed my hand at an MMR system based on hooks as well as k/e for killer only(imo the easiest to implement with hooks).

Before i begin i want to say that i am, in no way, a game developer, or a game designer, so everything mentioned here come from the point of view of a player and may contain some idea that are extremely difficult/impossible to do.

explanation:

I think we can all agree that, for killer, while kill and escape are the biggest factor to decide how well you did in a game, we cannot accurately determine a player skill through k/e alone.

My idea was change the yes/no that is currently in the game with escape/kill and add a With as variable that change the point gain depending on the hook state of the survivor.

Concretely, each new hook state is given a certain value that will be added to the point calculation at the end of the match.

Values + calculation:

Here is a list of all the variable that are present in this MMR along with the value that i decided, with the counting at the end of the game (no camping):

Escape: -10 if the survivor escape, 0 otherwise

Hatch escape: -4

1st hook: +2

2nd hook: +2

3rd hook: +6

So if the survivor:

Escape with no hook: -10 point

Escape with 1 hook: -10 +2 = -8 point

Escape with 2 hook: -10 +2 +2 = -6 point

Is sacrificed: 0 +2 +2 +6 = +10 point

Hatch escape with:

0 hook: -4 = -4 point

1 hook: -4 +2 = -2 point

2 hook: -4 +2 +2 = 0 point

In the case of a disconnect or a suicide (attempting escape to force 2nd stage, as well as failling skill check in struggle phase), all points related to said hook stage will be given to the killer.

Conclusion:

With this MMR system, escape and kill are still the deciding factor of the game, but you will lose less point in case of a 8h/0k since having 8 hook is still a display of skill, but will change the rare scenario of 10h/2k from a tie to a win for the killer.

The goal of only counting new hook stage, is present to disincentivize camping behaviour by making them gain less point for such gameplay, that way, a camped survivor will only ever grant 2 points to the killer making even a 3k/1e a loss (-4 points) in those situations.

The obvious flaw in this design is that a killer could lose points if the survivor decide not to save each other, making you unable to earn all 10 points in those cases.

I did my best to try and explore most scenario that could be make this system bad/less effective. Feel free to point out any mistake that i may have overlooked.
