Iīm not very familiar with 40k background, and while reading about each one of the eldar craftworlds something hit me. The craftworld Saim-Hann is renowned for being the oddball among the other craftworlds, because their customs are seen as more "wild and barbaric". Also it is noted that the eldar paths on Saim-Hann are less strict that on your average craftworld, and their culture has several similarities with that of the exodites.
The part that left me wondering is the whole less strict eldar path. For starters i donīt know for sure just how strict the eldar path is on a normal craftworld, so i canīt imagine what it means when it says that it is less strict. As far as i know, when a eldar is on a path (say, warrior path), he isnīt allowed to do anything else but focus on that, until he is finished. If he dabbles on something else, he would be breaking the rules, right? So does that means that the eldar of Saim-Hann can mix and match their paths to a degree? How would the paths be more flexible (with specific examples) if the whole concept is to restrict yourself to one path?
Finally, this piece of fluff left me wondering the validity of the eldar paths at all. If Saim-Hann can get away having a more flexible path system (with no big drawbacks, or else it would be at least referenced), then the question arises as to whenever the paths are necessary only to a point, and they donīt need to be as strict as most craftworlds enforce. Therefore it would be more a choice to be strict (as in, they think the hardcore discipline is good) rather than a necessity.
