NA Servant Upgrades you're most looking forward to

Now that we’ve gotten some of the big ones such as Jeanne’s NP upgrade, what other upgrades this year are you most excited for? Personally I think Nightingale’s is gonna be really helpful in her support role and might reduce how easily she goes down given her constant class disadvantage. What about you?
