I'm getting closer to TRing my lvl20 kensai fighter into ... well, another lvl20 kensai fighter. Reasons for the TR:
1. Move from a 28pt to a 34pt build
2. Reselect feats, getting rid of stuff like Luck of heroes and Lighting reflexes
3. Play at low levels with the awesomesweet toys acquired during my first life

Having several feats to spare (but not enough INT for CE -> Improved Trip, ****!) I'm debating whether the past life feat Student of the Sword is worth spending a feat slot over.

"You recall more about your past life as a fighter. You have +2 to your Intimidate skill, +1 to the Maximum Dexterity Bonus of armor and shields, and can remember your martial prowess three times per rest, increasing your base attack bonus to your level and granting +4 to hit."
How good is that? Has anyone experimented with it? Did you find it useful in any way?
