[4E] Simple fix for Int's irrelevance to trained skill selection?

[Aahz]

Here, there is no opportunity cost. That is the problem. Allowing INT to give more skills just gives Wizards, Warlocks, and INT Warlords free power - if you're fine with giving an arbitrary boost to some classes and not others, then fine.

??? In my suggestion, the "relevant" stat for the skill (Dex for Acrobatics, Str for Athletics) determines whether or not you can train it as an "extra" skill. In other words, if you have a 16 Dex, you can train one extra Dex-based skill.

I admit this would lead to skill bloat and reduction in the value of skill training feats, but the OP didn't seem to be too concerned about that. But I think it would be pretty evenly fair to all classes, since almost everyone would have a 16 in some stat.
