PS: I should say that I'm not complaining about the circumstances of the story specifically, like Caster reducing Atalanta's efficiency, but rather trying to understand why the human mages have to be involved in what amounts to a mass suicide by going face first into this death trap that's nigh impossible to cross even for one of the Servants most well equipped for the job in the whole of Fate lore.

Even sending other Servants there, instead of finding a way around, would be a bad idea in my view if it's so impossibly hard to get through this forest no matter how skilled at this one specific field of activity you are.
