Holy Crap!!!!
Every articulation is "fine", and most are far beyond that. You wouldn't play a whole passage with an fp... perhaps the label of this notorious articulation is not too accurate, but it has its place, I'm sure, and is probably very handy for that purpose. Maybe it should be called "perf-port" or "perf-leg_gl", but who cares? You listen to it, you don't like it, so don't use it. End of story!!!! This notion that you've somehow been "ripped off" is just stupid. It's already been explained why the forte perf-leg didn't turn out as expected during the sampling sessions, and that's that... (I remember something about a harmonic artifact, that became particularly noticable in the legato-transition recordings at forte. Now, I'm sure Herb made the best choice, given this symptom. It's probably worth note, BTW, that the "correct" perf-leg you're looking for may have sounded totally ridiculous with that sonic artifact included. And the fact is, you weren't there, so you simply don't know! I'd imagine, on comparing the artifact-ed samples with the slightly scooped ones, you'd probably be happy with what you got. Reproducing this sort of artifact over the entire instrument would likely sound completely obnoxious, and would also carry a profound "sample signature" along with it, thus still needing to be used sparingly and with great care.)
