What is the expected speed of progression on adventures and adventure path in particular ? I have read the first two for age of ashes and the expected progression is four level each, but evaluating the content, I doubt each would last more than 3, 5 hour sessions ..
So that means more than one level per session, which seems crazy fast to me (perhaps because I am an old grognard ;-) )
Am I missing something ? Are the adventure paths supposed to last longer than that ?
