Please dont call it skill rating its so inaccurate. It could be called skill rating if it represented YOUR SKILL but it doesnt. 20% of the so called skill rating is you while 80% of it is random 4 players you get.
In each individual game, sure, it does — and your win or loss is determined in the same part by the five random players you face off on the other team. Over many games, it reflects your skill.
You seem to be making one of the classic mistakes, which is to look at a single event, then complaining that something that measures skill over many games is inaccurate.
You kinda forgot that the random 5 players that you are facing can have up to 600 more individual skill rating than you. Which can lead to – If u cant beat someone with 500+ rating, you wont progress.
It can be called skill rating if the matchmaking is perfectly balanced and that will never happen in gw2 due to population problem.
To your, so called classic mistake:
Does it make sense that my skill rating that reflect my skill ( thats what you think i guess) will go drastically down in over a day. We are talking about 250 rating here. If the skill rating perfectly represents your skill that situation should never happen unless my playstyle went really downhill or the matchmaking of the game is bad.
Hmm let me guess which one will it be….
I didn’t forget that the random five players on the other team can have 600 more MMR than you … just like I didn’t forget that the players on your team can have that 600 more MMR.
The problem with “ELO Hell” or “MMR is inaccurate because team composition” as ideas is that every single thing you say is keeping you down because it can randomly happen to one team or the other … applies equally to both teams.
You are also mistaking “MMR is accurate” for “MMR is perfectly accurate, all the time”, which your argument would break, yes. However, why did your skill go down 250 points in a day?
- you had an off day, and played really badly today
* you have high volatility because you have not played in a while
* you have high volatility because, despite randomly matching with players better and worse than you, you still lose when expected to win, and win when expected to lose
* your MMR is higher than your skill, and it’s still moving toward the correct value (which takes ~ 100 games)
* you switched your build or class to something else, and suck at it compared to the one you played before (right now, at least.)
* you duo-queued with someone with a very different MMR, and that made it harder for the MMR algorithm to home in on your skill
* you played at a super-quiet time, so a broader distribution of MMRs in the games, leading to increased volatility
Ultimately, though, your MMR going down means just one thing: you lost matches you were expected to win, and didn’t win matches you were expected to lose. The people you were randomly matched with played better than you did.
Going down a long way means one of two things: either your personal volatility is high, or you consistently played badly despite it being low. Either way, your MMR was lowered to reflect the quality of your play.
Sorry, I know that’s not nice to hear, but … ultimately, your MMR will wiggle up and down a little around the target point, because it is always an approximation of skill. If it changes dramatically, though, that’s about you, not the game.
