People need to remember that in an 24 player content many times there will be a long wait before going in. It's not just 4 players, it's not 8, it's 24. And it's likely to have someone AFK, someone withraw, or someone just not ready. It could always be a different person too for all we know...

What I mean is, with larger content comes larger number of players. And with larger number of players, comes larger chance of someone being AFK, or disconnect, or of people that are busy right now and rather withraw, or people who just abuse it and withraw.

But you need to rememer that if you get a series of withraws it could be all different players and not likely the same player over and over.
