Can I skip Tribbie? (context below)

I have a Guarantee, I'm at 62 pity with no pulls but would be able to get Tribbie before her banner ends, but then I'm risking getting E0S1 Castorice as I'd have to start saving after getting Tribbie.

Or do I skip Tribbie as I've heard at E0 she isn't that special. My team would then be E0S1 Castorice as I have Guarantee ready for Character and Light Cone, S1 Sunday and RMC/whoever, and then pick up Hyacine on her banner?

How important is Tribbie AT E0 SPECIFICALLY.
