2 points of STR aren't going to be that big of a difference, and with DT docents, warforged AC is up there with humans (my math is showing 50ish unbuffed, depending on gear). I could shave a couple of points from either WIS or DEX, but where to put them? That's not enough to up STR or CHA by more than 1 point, I don't need the INT, and CON seems like the least useful place to put them.
Honestly, if I am going to change anything at this point, it will be to drop paladin levels in favor of rogue, and if I'm going to drop to 6, I might as well drop to 3, and now I'm in the wrong forum
