IIRC the NA first kill on Batraal post came with a comment along the lines of "We'll post strats in a couple of days to give everyone a chance to figure it out for themselves" amd was followed by a shit storm of people demanding strats and complaining about how not sharing hurt the community. A good shell is going to experiment with various strats anyways to find the party make up that works best for them, so the cookie cutter builds are really only useful for pickup groups and weaker linkshells. The weaker shells are going to end up going with the easiest group composition regardless of how many different set ups work.
