Previously, if you were in the "high enough" window of AC that an increase in AC made any difference, the bonus of the Dodge feat would make the enemies 5% less likely to hit you. This is kind of "meh" for an entire feat.
Now it's 3% separate dodge, which unless someone can tell me otherwise, is a huge nerf to an already underpowered feat. I happen to be of the opinion that all feats should be useful to at least some builds, but this makes this feat only used as a prerequisite for other bad feats or good prestige enhancements.
So here is what I propose, buff Dodge back to it's former lack of glory, i.e 5% dodge bonus.
Secondly, if it's not too much to ask for, increase the dodge cap, 25% is fine if (and only if) you're wearing armor. I think it should be 20% if wearing heavy armor, 25% if wearing medium, 30% if wearing light, 35% if wearing no armor. While wearing no armor your AC is likely to be low and your PRR unexistent. So you should at least have the option (if heavily investing in it) to have a decent chance of not being easily killed.
