If it works for you, more power to ya', I still think it may be just a bit more limiting on your end than it needs to be. It also pigeon holes all dwarves to be strong, but not necessarily smart or frail. That is why I created the flexibility of 2 increases, so a player can tailor their own character. Another way you could give those racial bonuses and keep everyone at a flat two, with two choices of a three increase is: their racial bonus is the only way they can gain a white die in a characteristic and gain a white at creation in there racial characteristics. This gives them a racial edge, but does not give them a racial power. This also puts everyone in closer level to each other, which, makes a game more balanced. Then in my two advances to a 3, and I think you'll find that you will very much like the characters you get out of it.
Glad I could be of help. Have fun playing the game we love, wish I could, but won't be playing again for a week (hopefully sooner), but here's to hoping right?
