Smoke screen is great for dampening enmity on other hard pulling dps or healer classes, shadewalker let's tanks pull without having to be in tank stance, dancing edge reduces slashing resistance on enemies, Huton boosts personal attack speed without having to use a combo (unlike mnk), 3 Aoe attacks (one spammable), the ability to stun or silence, 3 dots, plus goad, trick attack, and the ability to throw out attacks from range while running from aoes, plus low positional requirements.... id say they have a lot more use than you think
