Matchmaking: Huh?

This was my first match of the day. Two thieves? This happened at 11:45 AM PST patch day when a lot of players seemed to be on trying the system. I thought this system was suppose to prevent that? Some more info:

We duo queued
I was a thief
Friend was a mesmer
We both play our classes at a high level.
We got into queue on the first try.
It was BOTH of our first matches in the new system.

Looks like the matchmaker found a bunch of players with short character names.

Nothing to see here folks, everything’s working as intended.

Content in this game will always seem
to be faceroll at the high levels, because it
needs to be accessible to the casuals and bads.

Found a missing ‘+ 1’ (literally) in the matchmaking code. Will get this fixed soon.

In the mean time, it doesn’t factor in 2 of the same profession, only 3+.

Well, I don’t know… this isn’t suppose to happen twice in a row, right?

Glad you found a fix, and from my own experience coding for grad school I know how easy it is for syntax errors to sneak into code. Just curious (and I hope I’m not being rude) how do those kind of syntax errors make it through multiple layers of QA?

So you literally didn’t test queueing with two of the same class? WTF?

Or they did test it on different configurations and went to live on the wrong config

4 is treated as 3, which has score reduced by 2 * scorePerCommonProfession.
3 is treated as 2, which has score reduced by 1 * scorePerCommonProfession.
2 is treated as 1, which has no score reduction.

If you take a look at the wiki the score penalty isn’t that high, and it was being made to have even less impact because of this bug.

Tomorrow I’ll up the penalty when I get the bugged fixed, see if that set’s it right.

If it doesn’t work, I’ll also see about changing it to an exponential calculation.

A missing +1 is a logic, not syntax, error.

And it can slip through QA if QA isn’t specifically testing for it. Doesn’t make the results any less egregious, however.

Long story short, it’s my fault. We had bots and all that running and it was my job to validate that it was working as expected, I missed this.

Only caught the issue because I wrote a C++11 match simulator over the weekend and I was validating that it works identical to the real systems. May end up releasing the source code to that, which is why it can’t just reuse our existing C++ code.
