Honestly I see alot of whining going on.
You don't like what you're getting? Go cry about it. It's about chance. Luck. You could open one for the first time and get a Nihilus mask, turn around and sell it for nearly 2mil, or you could get complete crap. You might just be aiming for an item you want like a Heroes banner or glowing eyes. It's your fault that you bought it, so don't complain about it. Grow up.
