-.-/ right only people who know the job properly and know when to use it find it useful. it's fun to see people run around, specially blm's who think they know their job, disregard it as they get killed do to mobs which could of been avoided if they knew how or what bind even means.
They are not meant for DMG, they are meant for support during tight spots when tanks fail or hate control is needed. Specially if sleep is being resisted.
Short answer; yes it's useful IF you know when and how it's meant to be used.
Long answer; only someone who depends on others for survival would find it useless. ( no offense , it's just a logical and realistic answer. )
