KoTC has the light imbue in core 1. You lose movement bonus, deflect arrows and some ki generation but it could open up some options in other trees for less squishiness, like sacred defender. But you also gain long swords as favored weapons in KoTC tier 2 and Knight Training for free in t4.
My first iteration of the build was pally instead of sacred fist with kotc but sacred fist has just been much better. The feat really dont matter too much because the next best feat would be 2 more melee power from weapon focus and I get 5 more imbue plus the hugely important movement speed. I would also have to move enhancements around to put some points in vistani if I did not get the deflect arrows from sacred fist.
This build is squishy yes but I dont want to give up DPS or even pick up something like threat generation from the sacred defender tree. That would make this build useless in raids if it was in sacred defense.
As an aside you should never be in a fighter or pally defensive combat stance as a melee dps. You will turn a raid boss around and you will kill people.
