So a couple of my players are asking why they can't raise their Characteristics after Character Creation and I haven't seen any real reason not to let them. I'm reluctant to just allow it, but this was also their first time playing the game and with learning the rules they invested more in skills and talents then stats thinking they could raise them. It was only recently while going over the forums I found ouy you couldn't. The default is to let them completely redo their characters, but is asks the question "why can't Characteristics be raised?". And yes I am aware that the rules say you can't train Characteristics after creation accept by the Determination Talent.
I'm considering only allowing if a certain number of times, or raising the cost to account for "significant training time". Or possibly making it a talents at the top of every tree. Looking for Ideas or suggestions on either balancing raising characteristics or thinking of a good reason not to let them other than "it's in the rules".
