Well I should not say Choices as much as Diversity. Much like the the Zaishen Dailies of old.
Gather happens every day and you know what happens people get in a rut and go farm the same nodes everyday. Add more Diversity to it: so today its Copper Ore tomorrow it could be Leeks and the following day it could be Ancient Wood.
Daily Dungeon ask for a certain path.
Daily Kills ask for a certain mob.
I am sure more people could think of more Diversity to add to the Dailies.
