As the potential stat is the genetic maximum that character can attain, how and why should potentials be affected by stat gain rolls?As stated earlier, Stats max out at around 5th level. So, why have a bonus now, when you could get a bigger bonus -higher maxed out Potentials around 5th or 6th. This isn't cannon. I just thought it might be a good idea.
Perhaps genetic maximum is a bit rigid. IMO, genetic max
potential and using age modifiers could work also.
For me, people aren't only bound by genetics. Lifestyle, diet, training, etc. all play a big part in the characters' development. Rather than have rolls for each of these... give them a chance to increase Potentials.
Just a thought..
