I can still understand the need for videos for maps where you don't know what to expect from opponents and need a basis on how to prepare—as was the case, for example, in the relatively recent map "The Sovereign is More Alive than Dead"—but I don't understand why one would upload a video Walkthrough of this particular map, which is entirely based on fixed battles where the AI will not act identically, and therefore it will be impossible to perfectly replicate the tactics from the video itself. I can only assume that some people are simply too lazy to think and try replaying the battles a couple of times.
