Archers are the only ones I'd say are "hard shafted", and even then it's basically working on a time limit. Granted, that's only really something that would be exposed after revealing his True Name, but this is a Greater Grail War rather than a HGW, meaning it's not like singular class matchups are as big of an issue. Standard Protection of Arrows would be more useful than it even honestly, since this requires keeping it active, meaning he can get ambushed or attacked by Archers when not actively heading into combat. Even then, high-tier Archers like Arjuna or Arash wouldn't be rendered useless by it even if he DID just march in. 

Assassins usually have other methods anyway, and the emphasis on "has to be prepared" is even more accentuated here, since Assassins are specifically meant for situations like that, and plenty of them do so in close-quarters as well. 

It's up to you guys in the end, I just don't see this being broken.
