Logically, I don't see why you wouldn't be able to dodge an arrow or move your body, when someone takes a swing at you. I know you can't "step" aside, but if that save really was stepping aside when something hit you, then why is it taken after wounding?
Rulewise, I can't find it, so I'd assume they'd all still work. The skills says what they do, and I see no errata correcting it after Blazing Saddles came out.
Balance-wise, mounting anything above 20 exp would be a bit pointless.
All in all: They still work very much imo.
And why is Expert Swordsman an issue? Can't you be good at charging with a sword from horseback? ^_^
