Approx. Queue time; biggest conspiracy in history.
You watch (or play) the high elo players sitting in queue for easily over 10 minutes, yet the "approximate" time shown is always around 1 minute. While people learn to just expect it and ignore the approximate time, I think you should really update your system to be more accurate. I don't know what it takes into account to get that time, but it sucks and is not doing its job; just shoddy work that shouldn't have been implemented if it never worked in the first place.
