Angela rankup?

TheHoodedDormammu

Should I take my 5 star sig 40 angela to rank 5?
I can also put around 150 cosmic sig stones into her.
The only concern I have is that she might get nerfed or something since I'm mainly doing this for her awakened ability. I have all other cosmic champs at r4 and r5 except for CGR.
