Will patience really help me

I have 4* rank4 claire and I am in act5.2.
I have 3 t4 mystic catalyst. I really want doom and will rank him up.
But for now shall I rank her up or wait to get doom.
My luck with Crystal's are really bad
And I have only 3 star doom till date.

Had a 4* Clair brought her 4/40, next day got 5* Claire brought her to r3, right after that I finally got the 5* doom I’d been hunting.
