Roland use a command seal to throw an undodgeable durandal at em please

Well there is that one legend that says the sword lodged in the cliff in Rocamadour is there because Roland threw it all the way from the battlefield ( ͡° ͜ʖ ͡°)

But vance is right. It'd be cheap BS to say Roland could detect [i]and[/i] hit a moving target from this far away. She isn't Archer (plus, no matter how silly Servants' ability to sense each other can be sometimes, I doubt these guys are radiating their presences since they're not in combat). That and throwing Durandal would be a stupidly risky tactic, even if it is indestructible. 

No, if Albert wanted her to throw something, he'd use something else... >:D
