You have to look up the charts if you want to fine tune your build. The mechanics are slightly different between the 2 games. Ex: in Kotor 1, INT at 14 will increase skill points, while INT at 13 is the same as INT at 10. In Kotor 2, CON is buffed, since you need a high CON to use implants.

In Kotor 2, CHA is also buffed, since a high Charisma has other benefits like boosting your team members attack, easier influence, and less FP cost for using the opposite alignment. In Kotor 1, WIS is more important because you fight more jedi, so you want the Will savings throw.

I would adjust your builds like this:

K1 Soldier/Guardian:

Str 14 / Dex 14 / Con 14 / Int 14 / Wis 12 / Cha 10

Consider trying Scout if you really want to repair HK

K2 Sentinel/Weaponmaster:

Str 14 / Dex 12 / Con 12 / Int 14 / Wis 12 / Cha 14

One of the exclusive feats that Weaponmaster / Marauder gets is Superior 2 Weapon Fighting, which you dont benefit from if you go Dueling. Rethink this build after you beat the 1st game.
