[CapedCrusader]

That's a really tough one. Fighting, Throwing, and Shooting are intrinsic to so many things, replacing any of them presents all kinds of hidden problems. There are many Edges and Hindrances that affect those/are affected by those, not to mention things like magic items, cyberware, and super powers. And then there are all of the per-requisites that look for them. A lot of those specifically look for one or more of these Skills. If you replace any of them, there are things that will stop working.

Now - that being said - we are all waiting with baited breath to see what changes they are making for the new edition. We may have to make some allowances that will allow us to re-address this issue.
