I know, I already read the comments in vol.19 spoilers, it's just my imagination of the EP's system. That's why I think the non-existence of king's trait is the reason why some servants are stronger than their master, because servants have the trait of EP placed inside their body while the master doesn't have any piece.

ps: I seriously need to read vol.19 before making any possible misunderstanding in the the future. and sorry if my english is not good and/or correct, I am not a native.
