Help me make a fighter work

[Rhedyn]

I have less of a specific concept than just wanting a fighter with the fighter class features to work. The groups I play in are fairly well optimized and my GMs tend to run the encounters hard. I need to contribute as well as a normal partial caster inside and outside of combat, but I've always had the most fun as a fighter until I reach the point that my character feels incompetent or made of glass (level 9+ or so). I no longer feel like a fighter if I can't wade in the front of combat without exploding or having 6+ spell buffs on me. I have a gamist need to have some mechanical reason to be playing this class over another.

I want to know if the following build achieves my personal wants, and if it doesn't, how I can make that happen.

Want to contribute outside of combat? Fit this into your build:

Traits
Adopted (halflings)
Helpful (halfling)

Feats
Fast-Learner
Improvisation
Improved Improvisation

Now you're an aid another MACHINE. The one drawback is that you have to bump Int up to 13, but that opens up a bunch of good feats anyway.

How do you feel about dipping into other classes?

1. I think your build achieves your wants. All that Versatile Trainings should do the trick. You could even tank INT and boost CHA, replace Armed Bravery and Adaptable Training with Improved Bravery and Social Bravery to boost your CHA-based skills. A Human Fighter with 10 INT has 3 skills per level. A Human Fighter with 7 INT has 2 skills per level because you already reached the 1 per level class cap.

2. If you could go NG rather than LG, you could go for Additional Traits in place of Blind-Fight to pick up Blind Zeal for Blind-Fight and Dangerously Curious for UMD class skill.

Does it have to be a fighter? A Slayer is just about as good as a fighter in combat, but can contribute out of combat as well without jumping through lots of hoops.

Did you see the build? A Slayer is extremely vulnerable in comparison.
