Given the new idea of a skill-buy and given the fact that feats have always been able to alter feats a bit, my brain inevitably goes to the idea of buying skills with feats as an option.
What I was thinking:
One or multiple feats that do the following:
1) Buy one crossclassed feat not taken and make it a taken class-feat.
2) Buy two class feats not taken and make them class feats.
3) Buy two cross-classed feats taken and make them class feats.
If that is too powerful then:
1) Buy one class feat
2) Make a taken cross-classed feat a class feat.
Given the fact that certain classes are suppose to be skill monkeys... i dont think adding skills at full rank progression to other classes is necessarilly balanced... Paizo already has increased the overall number of skills that non-skill monkeys can use dramatically...
a 3.5 Fighter with 10 intelligence at lvl 11 had 2 skills(assuming he wants to max out ranks: 14+stat for a class skill or 7 if crossclassed). A Paizo version fighter has 7 skills. That's a skill increase of 350%... don't think they need an additional boost.
Additionally, since the new method gives you a rating based on level, the non-skill monkeys can venture out into more skills that aren't iconic to his class...
Yes, but you would be gaining such in trade for a loss of feat.
If it was the second list of options, then first of all you would have already needed to spend one of your skill-buys to receive it as a cross-class...then have to give up a feat to make it class.
