I suggest devs look at turning the ability to pack up our thralls back on a week before implementing the new system so people can store their thralls.
They can redeploy them after implementation when they feel comfortable with it.
The mechanic to packing up our thralls was in game before we used to do it. Let us do it again in a time limited basis a week before and that should lessen peoples anxiety about managing and learning the new system when its implemented.
I am not in favor of this new implementation because I thinks its just to much micro management but if i can pack up my thralls prior I can at least tinker with it when implemented.
