I appreciate Valve's dedication to this game, but I can't help feeling that the game was better when everyone was on a level playing field to start with. Achievements are okay but when they cause people to play the game in a non-beneficial way, then what good are they?
If anything, this update has shown us how sensitive they are about the achievement system. They have an obvious emotional investment in it. Unfortunately, that means they are unlikely to take a deep breath, step back a little and objectively look at the bigger picture.
