Me (mainland US) to New York
Some random guy 2 countries east of Turkey all the way to a country north-west of germany
Oh will you look at that... I'm STILL further away... let's not begin the 'extremes' argument.
If you were looking for the fairest match-up on a single server, you should have tried to set up a UK server. USA pings would have been around the same and Turkish pings would (I believe) have been a little bit higher (but still lower than USA pings) to even it up as much as possible. (I could be wrong, but I'm pretty sure that's how that would work out.) Or Turkey could just respect the fact that they are supposed to play with the home-away system outlined by Rey.
Preferably though, the administration should manually change some teams around so that the teams furthest away from each other don't end up in the same initial groups. Let the teams at least start the tournament off with somewhat legitimate matches. Hopefully that way, one of the teams gets eliminated before they even have to face each other in the tournament, and if somehow both teams meet at a latter stage in the tournament, at least they had a more decent path leading to that inevitable moment.
Personally I think this USA team is really bad and doesn't have a chance of winning anything, but at least TRY to set up some fair matches for them
Why even let them sign up if you're just going to screw them in a "nations" cup with horrible match-ups?
NC2017 - Team NA gets a fair way into the tournament because they don't get insta-screwed by an impractical match-up.
NC2016 - Team NA in a group-stage with Turkey
NC2015 - Team NA has it's first knockout stage match against Turkey, lose the same way because the whole match was also played on an EU server.
NC2014 - Team Canada in a group-stage with Russia
NC2013 - Team Canada in a group-stage with Russia
I feel like you could take 5 seconds to look at the groups you've randomized and say... "maybe some of these matches aren't practical, we can make some minor tweaks to make it better for the participants"
Just something to consider now or in the future for NC 2019 whether it be here or in Bannerlord.
