Using Force Sensitive and Force Feats in a DnD campaign?

[Blue Sky]

I used the rules for a Dark Sun game, once, as a replacement for psionics. I just ruled that it did subdual damage.

It worked out pretty well, with the exception that barbarians had the most reserves. With the high psionics level of Dark Sun, it also meant that most fights ended with a knockout, instead of a kill.

Did any of you find that the Force skills and feats were too powerful for your game?

I'm thinking that characters with high hit die (d10, d12) would be that much more powerful having access to the Force.

For example, a Fighter having his bonus feats and Force skills. Would a fighter only have 2+Int skills per level balance this out?
