I agree with initial post - Utopia seems to be split between KD's that understand keeping this up is a good idea and those that has not yet realized this/or is incapable of getting a Barrier up every 5 days.
KD Rituals is an interesting new mechanic I think - but in it's current state Barrier seems too strong. For next age I'd like to see the elements of Barrier ritual split into either 2 or 4 different rituals - Duration and cost can be tweaked accordingly.
