i am strongly disagree, sussur weapon is great. i usually craft a dagger and give to a dual wielding astarion, so he cam land crits and also cast silence with the sussur dagger
for example remember the guy before orin's nest whom you need to kill in 5 turns or insta death? if that guy will get a silence debuff his curse on you would be lifted (at least it woirked for me like that a few patches ago)
silence is very useful
