I've been playing SWAT, Team Objective, Action Sack (Speedpile doesn't count for the achievement apperantely) BTB for hours and I didn't even get a chance to vote for Stockpile... It's easier to get a 50k Jackpot, then to find a game of Stockpile -_-
I remember playing Reach in January-February and I got to play Stockpile frequently. What happened??! My friends and I are pissed, because we wasted a s**tload of time, trying to get that damn "You Ate All The Chips" achievement, and no luck to even find a Stockpile match. It's the last achievement I need, and it's more complicated then any other Halo: Reach achievement. I even had more fun playing solo on Legendary then trying to find at least one match of Stockpile...
If you removed the gametype, then remove the blasted achievement!
/angry rant off
Thank you, for your attention...
