If I were you instead of making threads saying this you should post this in those members' thread. Most of them pay a lot of attention to thier threads and they will notice that you are talking to them about their problem.
We are getting to many threads with members complaining about comparisons and then we have threads such as this with people complaining about complaining. I think we now need a thread to complain about complainers that are complaining about these changes.
I agree with you completely on this. I would say to some of these members that if you are bashing on how bad you assumingly know Halo 4 is going to be, then I am glad that you are not getting it. I wouldn't want to play with you anyway.
I'm not criticizing you, I am just asking that since you have the balls that you should take it to the source. Just remember not to fight with other members. Just make your statement and do not communicate much farther with that person. Don't worry, they will be affected by their opinion if they are optimistic whatsoever.
