Looks like at some recent point in time (I didn't do them essentially only for the duration of the Midyear event), both the Elsweyr and Murkmire prologue repeatable quests given by Zahari and Jee-Jar changed from being all of them repeatable daily to more like daily WB/delve -- you get only one per day.
It is especially bad when you consider that not enough people do them to share (IF they are shareable -- I was unable to find anyone in three days who'd do it) AND the Cyrodilic Collections Champion achievement was not adjusted to accommodate for the change, still requiring the insane ONE HUNDRED AND FIFTY of them done.
@ZOS_GinaBruno -- was it an intended change or did someone mess up? I really hope that if it was someone's idea of "tuning them up" for the upcoming Elsweyr celebration, it gets reversed. The only thing you achieve this way is frustration and people NOT doing them anymore.
