Well some of the concept behind this game are really good, but the actual implementation is bland and lazy (at least) and on top of that if you wanna be f2p you need an incredible amount of time to just be somewhere decent, as the grind is just one of the peak korean-style.
Considering that the combat is incredibly cluncky, boring and purely stat based, i can't see any point in such an endless grind.
