The whole "XXXX+" game thing is incredibly aggravating to me as someone whose Dominion skill seems to pretty clearly be 4800 on goko's system. I rarely get to play games with players better than me, and as such I don't get to increase my skill by learning from those better than I am.
The only time this annoys me is when I see someone rated 5100 who is requesting 5000+. I usually try to leave a 1000 point or so gap below my rating; there's no good reason to play *only* people who are better than you.
However, this is really just a reminder that real matchmaking is needed.
it's legit though. there is no law that requests that your own ranking has to be in the scope that you're asking for. if you open a game you make an offer for others to play with you. and you can offer whatever you want. you could be 3000 and ask for 5k+ if you wanted, and even that would be fine. it only annoys you because you automatically assume a certain ranking from the host based on what he's asking for. so it's kind of your problem.
Well, really it's not my problem at all, as I don't join other people's games unless it's been set up beforehand.
However, it's a matter of... courtesy? Maybe. Given that the intent of most rating systems is to match players of similar rating, it's a bit silly to ask for 5000+ when you're 4000. Obviously that's up to the game's host, and anyone joining the game can check the host's rating first. I'd probably just blacklist someone trying to do it, though again it doesn't matter to me because I host.
I think it's... pathetic, in a way. It's like saying: "I'm actually better than other players at my rating, I've just been unlucky." that's something a lot of people want to believe, especially if they're unhappy with their current rating.
also, they could see their rating being more likely to go up when playing vs high ranked opponents. i generally feel like, if your only goal was to get your rating up, you should choose opponents that are as high ranked as possible. you're obviously less likely to win, but i feel like goko factors rating differences too much. and even if that isn't correct, some people will think it is.
either way, it makes you look kind of bad, but it's still legit.
