I don't know. While I can really agree with you that there's a lack of regen healing with the loss of collective unconscious' old effect, I personally like the ability to stack the two shields together to provide a stronger defense against ride wide mechanics like a Scholar can do with deployment tactics.. Making this change would allow Astrologian to compete more in one area but lessen their ability to compete in another, making their only window to do this sort of thing in neutral sect while in diurnal.. Which I feel would just shoehorn the class even more into that sect.

I'd like to see them add an additional regen effect to Nocturnal as well.. But I feel that it should be separated from making any changes to Diurnal and shouldn't reduce their shielding potential which is already lower than Scholars.. Like possibly just giving Horoscope a regen effect if evolved to Horoscope Helios while in Nocturnal or evaulating whether maybe just adding a persistent regen back into Nocturnal collective would be overpowering.
