¿Sado Revision?

Since i´ve been playing so far i have noticed that Grua Tirar and El Directo (Skills of Sado) have more or less (or exactly) the same damage, or at least the same scale of damage. So i was wondering ¿why not to propose a check up of those skills and see if the ADM´s rebalanced them?. I think it would be the best option, since one Skill is higher leveled than the other. It would be normal if one is stronger, but right now both are the same, or at least thats what i´ve been seeing so far.
