I've always considered Draw Out to be one of the best "all around" secondary skillsets you can have, and really can be almost as damaging as Agrias' special attacks in some cases, and provide many other functions like Kyomori, Murasame, and Bizen. Samurai in general has moderate attack and defense, and their Hp is on the low side (specially for a heavily armored class). I would give the samurai class a 6/10 on the usefulness scale. Decent but not great. But I think they made them that way to make people really work for their full Draw Out, Two Hands, and Blade Grasp abilities. Almost every single one of my game ends up with Ramza using Guts, Draw Out, Blade Grasp, Two Hands (or Attack Up if I really need the shield), and Move +2/3. He basically becomes a pimped out samurai with a huge Move statistic and the ability to two hand a knight sword.
