I noticed on the Eastern Gateway, 6:30 - 10:30 (-0600) are the most skilled players.
Three months ago when I started playing again - I realized that Blizzard doesn't just sort by Rank. They factor in Ratio too, maybe other variables... when I was 31:0 beginning (chim rushing) - I always played people who never lagged & computers loaded within 15 seconds of mine (very beefy custom built computer).
After that binge where teamates demanded I push hunts in 4v4's & my ratio went negative - I suddenly saw lots of laggers & dropping players.
Basically, it's like the cast system - all of the have's (dsl/cable/new computers) lead to good ratios & fun games. While the have nots, just get each other & become bitter over the whole experience - then start leaving games prematurely - ever seen someone lose a hero & leave?
Just for kicks, I found this:
