It is more that AOE 2 doesn't really have a meta right now, and the community more or less understand most strategies doesn't work in campaigns.
I watched some of Kiara latest AOE 2, and the things the chat was malding over were pretty reasonable, for chats standard, like when she had trebuchets and still ran her army under towers and took a lot of unnecessary loses, even though she knew what the trebuchets did, but other than that, it wasn't that much overt back seating going on that was anything to mald over, and the chicken did a good job in curbing it to a good enough level for her.
