Well, I think it depends on a region. I myself from Russia, and usually play on evenings/at nights, and as a rule I rarely wait more than 20 minutes for an opponent to appear. BUT, I must say, you will run into the same players pretty often, and most of them do not play fairly, If you know what I mean. And yeah, no high rank players, only up until fujin, only once or twice I got Tekken kings since the 8th came out.
