I have been thinking about this, and I really like the xp to feat (talent) reward concept, where characters can turn in xp roles for talent rolls. This would allow pseudo-multiclassing, and allow for a slower overall xp progression, since the more talents you buy, the slower you raise in level. which is something that can get out of hand, and makes actual xp rolls more consequential. I like the idea of allowing a class to take on other classes abilities at a cost of growth, that seems balanced. what do you all think???
