That depends on what exactly you want. If you're going for pure melee, Soldier-Guardian is hard to beat. If you want massive Force Powers and good saves, Scout-Consular is a nice choice. A balanced and versatile build would be Scout-Sentinel. Want to solo through the game? Go Scoundrel-Consular. For a "Magic Swordsman" type character, Soldier-Consular is good.
So it depends upon what exactly you want to do.
Everyone is entitled to be stupid, but most abuse the privilege.
odd. i have beaten this game like 15 times, yet I have never been a sentinel or a scoundrel. On KOTOR2, however, the only thing I ever play as anymore is a sentinel.
the best class combo would depend on wether you want feats or skills. For feats go soldier-guardian. for skills go scout-consular or scout-sentinal. for all skills and little feats go scoundrel-sentinel. My personal favorite is: Scout-consular. S/C can have high repair, Comp. use, persuade,and treat injury.
