I like, for example, instead of a numerical system in which +2 (whether it's + to % rolled or two extra d6's in dice pool) for lining up shot and -2 for poor lighting = no modifer, the WFRP pool means 2 fortune and 2 misfortune that may or may not cancel. On average they cancel but instead of no change to your probabilities, they increase the chances of better or worse outcomes (essentially they extend the back and front tails of the bell curve).
My thoughts exactly! The SW dice pool is actually better and simpler but still gives you the nuances. The SW system generally has a lot going for it. If FFG were to go back to the percentile system completely then they might as well shift to d20, which is more used than percentiles.
