I am not a fan of stat dice rolls in cRPG. It is an interesting concept - having an ability to simply roll a weaker character. But in Table-Top GM can craft experience depending on how game develops. In cRPG making power of player character randomized, on top of player's competency only makes devs job harder - how do they craft fun experience, if player rolls a crappy character? And would a new player know if they roll was good enough? Or will they invest 15-20 hours into the game, only to realize that they are behind/in front of enjoyable difficulty curve because of a roll they had when they started the game?
