Wow. That's one of my least favorite changes to FC. I always hated in core d20 that skills were treated as afterthoughts, and liked the way in SC the feats linked to skill pre-reqs enforced some internal consistency and made a meaningful connection of skills to combat.
I'm not sure I follow here? All I want to get rid of is level and base attack as requirements, not change skills.
Sorry, I was alluding more to the b/m/s type feats that have skill ranks as prereqs (ambush, mingling, etc.). Perhaps we are mostly talking about different things.
Though I'll note the absence of the bab prereq makes heartseeker less meaningful.
Unless you mean "combat skill", in which case consider 3 feats invested to be a good indication of skill level. Plus 90% of games I've played in don't get to 12th+ level, so "supremacy" never really comes into play, which is something I love about mastercraft.
WRT the skill related feats, that's one reason why the skill-rank-extender class abilities and feats (scientist class, untapped potential, etc.) more desirable.
I will say despite not liking the change, I recognize that it works, but it seems to me that part of the reason it works is that the feats are a bit smaller in scope, making them more on par with any other choice the character might have.
