In my opinion, since played different kinds of private servers/original KRO server:
Sinx origin were always fragile, but grant with greatly offensive power than lord knights/paladin :th_e8:
That is why sinx defensive barrier were worst than paladin(cloaking, edp, grimtooth, sonic blow(melee), soul breaker(range physical attack but need max INT that will never miss)
Hope the incoming "sinx soul breaker weapons" will get the same par with "sonic blow sinx weapons" :th_e30:
