343i, can you pretty please fix the achievements?

By that I mean make it so we at least have a better chance to get them. The achievements where you have to do something on a specific map are just annoying. Like the “All Alone” achievement. You have to be on a defiant map and be the last man standing. Getting last man standing can be pretty tricky as is. But on top of that, just getting the right map is annoying as all hell. I have played alot of matches and I rarely see any DLC maps in the Living Dead playlist. So how’s about you guys tweak those achievements so that we can get them on any map, Hmm?
