There must be tens of thousands of places that people have linked incredibly useful tutorials on the old wiki. They’re found in search results, forum posts, tweets, blog posts. With the new wiki these links are all broken, instead they lead to a single forum post, making it very difficult to find the information.
For example searching for “UE4 get all actors of class” online finds this answerhub post, which references a tutorial that is no longer there. Even searching for this page on the new wiki results in nothing. Even clicking on the “Learn” tab within the Epic Game Store takes you to the broken wiki forum post.
The forum post mentions a legacy wiki, which goes to a dead page. It seems you have tried to preserve old pages, why not forward to those pages?
