Only time you use focus instead of meditation is if you wear non medable armors (jackals collar). I prefer to use 2mr mage armor (leather) and med instead of jackals or any non-medable armors.

Chiv you should get to about 70 and keep your karma up. This will ensure you dont fizzle often. You don't need 4/6 for chiv either. I run 3/3 and do just fine on my warrior. I do however have aids.

Personally if you are making a warrior type, you need to build the template around a weapon. If you have a nice kryss, use poisoning. If you have a nice ornate axe, use anat, tactics and lumberjacking. Could go on for hours with this.

Bushido is only good for lightning strike and confidence anymore.
