This would be nice if only to have a slightly more accurate estimate of time.

I don't trust the DF average wait timer because it LIES. When quing for PvE, at least I can roughly estimate the actual time based on how many/what jobs are qued. Which means that if I have to use the restroom, or grab a drink, or tie my shoes, or whatever, I can ballpark if I'm gonna make it in time for the que. I can't do this for PvP ques because I have no idea how many people have qued and the timer is almost always WRONG. Something like this would be much more convenient.
