Since OP lacks context, we reverted back to old rates and events. Now, the nanny will only imprint on Thursday, Friday, Saturday, and Sunday. The poll is asking if users would prefer if the nanny is on 24/7 (the "Always and Forever" option) rather than the current setting only during the weekend events.
I personally would prefer 24/7. While imprinting is powerful, the vanilla imprinting timer is poorly designed. Requiring static intervals often means the baby needs to be imprinted in the middle of the night, and players are human beings who need to work or sleep. While yes you could simply ball the dino until the weekend, that essentially adds one to three days maturation times to all dinos, and maturation rates are already too low in my opinion as is.
