Grailing those with high NP levels is a good idea! They would benefit from the even so slight damage boost from 5+ levels.

In my opinion, unless you want to make him/her special, never grail a SSR Servant. Personally, aside from my other bro Emiya, I don't think I will grail any SR. They are strong enough as they are, really.
