This is a topic that has bothered for a long time. I really do have a hatred (that word does not do justice to the true feeling) for these things. Short answer, do not bring these things back.
Long answer…
So with the exception of Halo 3 ( I will get to it in minute), the last few Halo titles have done a decent job of keeping these out with the original 1000GS. My question is though, why add them later? Is it really hard to see how much people hate these things? I have not heard of a single GOOD reason to why these would be fun. These things ultimately do one thing though, break gameplay. I am not talking about progressive Achievements (though Running the Show was awful), I am talking about the ones that require HIGH amounts of dumb luck.
Aside from people getting upset and rushing for the Laser or suicide driving vehicles to the center of the map, there is boosting. I am not frowning on those who do that for those harder ones (I am guilty of that). I am frowning as to why you would continue to put these things in the games anyway. It is not a secret people get together to do this, they even have game nights listed on here! If you can see that, why will you not stop? I just want to enjoy the game or new maps. I have had no fun getting these. Ever. Period.
I once heard somebody say that these were the best because of how satisfying it was to complete. While it is satisfying, I do not want to be ripping my hair out for these things. So that opposing claim seems to hold nothing to me as it still does not help the issues already stated.
Halo 3 is no Saint when it comes to this. This game had by far the worst achievements. Perfection? Seriously? It is Halo 3, not everyone is THAT good. Average players were left out on that one. We were even lucky enough to get them at launch too, with things like Two for One and Maybe Next Time Buddy. The worst part is that Bungie thought it would be an awesome idea to include, no ONLY include some of these things in ranked playlists. This meant that people could potentially get banned for achievement boosting because it could be mistaken for skill boosting. Words cannot describe how sick that makes me. Even MS said it was okay to Achievement boost, but you could still get banned in Halo 3. This does not happen in the more recent titles, so it seems we have come a little way.
Halo: Reach had another problem, missing DLC playlists. Even 4 still has this problem (I could be wrong on both of these though). This is bad because no matter how hard it is, if there is no possibility of getting the correct maps, you are not going to get it. Period. With this issue, ALL Achievements should become available to EVERY map in the game.
So with my issues laid out I hope someone at 343 sees this. It is so easy because if they listen, they do not have to do anything. They can just ignore them and move to more important things. With this being said, I am VERY happy with the difficulty of the Campaign Achievements and I do not think they need to crank it up further. I like them challenging, not frustrating. Thanks for reading.
