Should we be limited to only one craft class?

[Darium]

going to tell you just like I told the OP, chances are, they aren't going to limit your levels, but will instead limit what you can make and what abilities/traits you can use. A "mastered" class may have some insane ability that lets your next 20 synths be auto success...you never know.

And how would you feel if you could only master CON?
