First of all, "The reload animation is different between games" is not trivia - if it was, it'd be repeated on nearly every page.
Second, the [[BF:IRL]] policy exists because generally people come to the Battlefield Wiki to learn about guns in the Battlefield games, whereas a place like IMFDB is a better place for such commentary as it's a gun enthusiast's website. It's a policy that keeps the main body of articles unambiguous as to what is portrayed in game (as opposed to what isn't).
Main point: not all of your edits have been reverted. Some have just been corrected for spelling and grammar. Others have been trimmed down to remove superfluous information and unfitting language. Obviously some have been outright reverted, but sometimes this is necessary.
The Admin team are not infallible but in general we know what an article must look and sound like to follow [[BF:MoS]], and any changes are made purely to that end. I try to explain exactly why I made changes in the edit summary but this is not always possible. Remember, you can leave a message my [[User_talk:FluoxetinePatch|talk page]] if you want to discuss revisions or if you need further guidance.
The somewhat harsh truth that all editors must make peace with is that there is always room for improvement, and usually that comes from someone else, but in of itself this is a fundamental strength of the wiki format. Instead of making posts complaining about every change you should either discuss them with us or adapt your style. Growing that thick skin is the first step on the path to being a self-sufficient and competent contributor, and I genuinely want to help you do it.
