[quote=@Sublimation] Your overestimating servants here. Rin with her special jewels can kill almost any servant with a surprise attack, they are A ranked attacks by the way which are lethal to a servant body. Kuzuki, albeit with reinforcement, is capable of defeating Saber, of course he has trained in an assassination school for almost all his life. Emiya naturally can have a defensive fight against a servant with projection. Emiya Shiro without any knowledge of his abilities managed to live more than "5 seconds" against Lancer, albeit with Lancer not being serious. A half rate reinforcement poster can block a light thrust with Gae Bolg. Etc. Oh by the way, Kotomine Kirei using command seals can fight servants. Hint hint. [/quote] Depends on the Servant really. Rin spent up almost ten years worth of stored Prana to kill Herakles once, which isn't exactly a feat you can do more than once on short notice. I would argue that Kuzuki would have lost had that fight gone on much longer, since Saber was becoming accustomed to his fighting style. Which is why he bugged out when he did. And I seem to recall most of Emiya's fight with Lancer involving him running away and getting his ass kicked, with nary a chance of him actually winning in sight.
