I would say that Indecency is correct, at least for the most part. I feel like there are enough pug groups out there that at this PugHub is not a "central" pug group. If there was literally 1 pug group that everyone went to then people would actually join. The only group where I would not say this works with is Invite players who should have their own pug (or whole system). Sadly this game isnt big enough for Faceit to actually work, either that or puggers are super needy and will never be happy with any system that is given to them.
And also if you are one of those Joes, Jibs, who got fat kidded from the A pug and dont want to play B pug. Why? Just play the B pug.
