i definitely agree with that idea bluddy - characters from the same time period having the same strengths and weakness in in using different types of magic. Death needs to be painful but not too bad and as such this allows you more cohesion over a series of characters with one specialized style.
(but i kind of like the randomised innate enchant being unique for every character and so lost (replaced by another) on death - not too painful but enough to make you respect your health bar a little bit more, not game breaking if lost, and also offering up more variety to your game over a series of characters through the varying innate enchants - would also encourage experimentation with different spells and builds, that is - specialization in slight or very different ways over a series of characters?!)
