Should I use all my masterclass starglitter?

So I already spent all my money pulling for Xiao and the pity I saved up for Hu Tao got wasted on Keqing while I was trying to pull for Bennet constellations.
Anyways, I have 74 masterless starglitter and am able to get 14 intertwined fates from it. Should I do it? I'm not really interested in the shop for MS so...
