Just when I thought you guys had achievements figured out, here you come with some last-minute ones that exemplify poor achievement design. Anything that affects the way people play, especially if it encourages sub-optimal tactics, is inherently bad. When you are in matchmaking you aren't just on your time. You're on everyone else's time. And when you screw around and keep doing things you wouldn't normally do instead of actually trying to win the match, you're ruining other people's time. I pay good money for XBL. Time is money. Time is valuable period. I don't want other people wasting my time. MP achievements encourage them to waste my time just to increase their Gamerscore.
