that just seems to make things more complicated....
anyway, the difference between DW and AW in regards to stat progression. you nailed it on the head mr. pfaff, in AW each job is very regulated in what it can and cannot do. it has fewer moves and a fairly limited advancement progression in regards to upping your stats. DW gives the player a lot more freedom to do what they choose, something i personally like. in exchange for this, you need to define you character to some degree when you create it. the way this seems to be done, not counting bards starting moves, is by which stats you choose to be good at. if you just go by the bonus, it would take you three stat increases to go from -1 to +2, while with the stats it will take you four. the stats are there to slow down the progression of the characters.
the advancement system on AW and DW also differ to a significant amount. there are no advances in DW like there are in AW. you get a move every level, period. in addition to this every 3rd level you get to up a stat by two. in AW you need to specifically pick to up a stat and forgo any other advantage you could have gained.
