Do you roll stats in DnD and then decide what class you are going to play accordingly? Strange, if a game should be at least a kind of fun, but ok in some way, and certainly a kind of roleplay, however not to my taste. Otherwise, if you wish to play as wizard and have to accept a rolled 10 in Intelligence, that's brave indeed. But is it from the "real world"? I'm a weak and lean person and would not try to excel as Fighter or Barbarian in Faerun. But if I trained a long time as Wizard or sold my body and mind as Warlock or Cleric to a higher power and then faced very low stats in my allegedly trained/granted abilities, that would be odd.
