Supposedly high level feats will be "tremendous" and much cooler than the existing feats. So, they're pretty much going to be more effective than +1 to a stat.
Sure, your first couple +1s are well worth it. Get that Dex up to a 20 (+1 init, AC, attack, damage, saves, checks? Don't mind if I do) and maybe change an odd score or two. Upping evens to the next tier for two feats though? Be hard pressed to make it worth the wait, especially with feats already doing much of those kinds of bonuses. Why increase Con when you can pick up the upgraded version of today's Durable kind of thing, plus another feat.
Anyhow, that's why I'm thinking more and more that +2 to a stat is a better balance point. Even if it's _still_ unbalanced because Dex is better than Cha, by a long shot.
hmmm...
...maybe there's "paragon" feats that give you +2 Stat in order to keep up, but you have to be level X to take them.
Although personally, I like the idea of a +1 just getting passed up, myself.
