The question should have probably been removed, but there are 2 apparent problems:
A) The question is old (+1 year)
B) The question has too many views (+7k in over a year)
In my opinion, the OP is asking many questions in order to solve one issue: Should I read the manga or the light novel?
He even mentions that the reason for posting his question is that there's still no season 2.
"As the anime stopped at season 1 and there's no news of season 2 yet"
So now, he wants to know what he should read. The answer everyone gives is the light novels. The OP also asks for mistakes in the manga's translation, but that's because the manga is his first choice in his question. Once he gets to know the novels are better, he would obviously want to know about the novel's translation.
So making a summary, this is what the OP is asking:
Should I read the manga or the light novel? What differenciates one
from the other?
Is the translation correct or will I get wrong info while reading it?
All the answers are on point and tell us what the OP wants to know (including Akamine's answer. The translation he provided seems to be aimed at one of the OP's queries as I explained before. With his character-per-character Japanese-English translation it is better understood though. I think the purpose was to let the OP see firsthand how the translation works, whether it's literal or not, whether it makes mistakes etc.)
Bottom line: I wouldn't change the answers. I would let them be as they are.
I wouldn't really change the question either given that the answers keep quoting it, but rather I would add something in the end like this.
To make my question less confusing and more comprehensible:
Should I read the manga or the light novel? What differenciates one from the other?
Is the translation correct?
Edit: Second option. If the answer doesn't comply with the standards, just close it. That way people can still see the question and answers as it's considered a question of relevance because of its views, but there won't be more answers. It will also deter new users from asking questions in the same way because the answer got closed.
I made this question some time ago. As you can see, it got closed because it doesn't comply with certain standards. However, the question is super popular and got several answers, so I asked a moderator whether I should ask it again in a different way for users that may consider it interesting. The answer I got is that there's no need, the system is made so that my popular question and its answers will be able to be seen by everybody, at the same time that the site applies the correct regulation to the question.
