How did you even get to level 85?

Most people don't remember being newbies. I'm sure every player was at this stage before (if not in WoW, another game). Remember when there was agility on warlock set pieces? Even blizzard didn't understand itemization, but when I was at this stage, I spent 5 seconds hovering over the stats in my panel to see what they did. The difference being illustrated is not the gap of experience, it's the gap of being able to deduce, investigate, and infer simple information about the game and put that information to use.
