I hate to use the house rule argument, but it is rather easy to house rule: Give all players all aptitudes. Maybe we can get FFG to make a little black optional box explaining this possibility and its merits in the rule book.
My worry about the current aptitude system is that I am unsure of how well it is balanced between the aptitudes and if the background and roles provides a free enough aptitude choice.
This is one of those things that's so simple you kick yourself for not having thought of it. Sure, it's a band-aid for the wonky Aptitude system, but using this rule I could just sharpie in a number at the top of each Talent table and on this Skill table.
Not sure what I'd do for characteristics, though. Maybe have each player pick 2/3 cheap, 3/4 medium, rest expensive options. Or use Aptitudes as normal... Still, I like it.
