The only time this bothered me was in Gears of War 3. I labored for weeks to get the Silverback leveled up so I could get the rocket shooting achievement and then discovered I needed a DLC pack to unlock rockets. I was mad, but GOW3 was so much fun, I gave in and just got all the DLC through Season Pass. Seriously, though, they should never update the achievement list before you buy the DLC. That's just dirty pool to me.
