Okay imagine Blizzard as a father, mother, or guardian taking care of thousands of ungrateful, self-indulged, whining, stuck up children that don't know whats good for them everyday 24/7 7 days a week.
Completely doctored stats. They take ALL chars into account for their stats. Given that probably 50-60% of all characters are mules, or under level 5, it's complete BS.
I'd estimate about 30-40% of all players are in Inferno. Probably more.
No need to use the DVD at all, the only thing that matters is the game key inside the box, which you can apply to your Battle.net account. Then your pre-downloaded install will work exactly the same as having installed from the DVD.
Didn't think about this, completely agree.
