I think blader's shouldn't kill with one hit while in bm2 ... they're fast + lethal(or critical i don't know) strike they're unbeatble in PvP. I think a game shouldn't have a "better" class or everyone would start making bladers.I'm a warrior and i can't kill my friend(blader) because when the battle starts he use uses that skill and i'm already dead in 1 second. I don't know if my gear and status are fine to PvP but even my guild leader says blader is unbeatble(my leader is a blader).
My suggestion is to lower the chance of giving criticals to bladers so warriors may have a chance against them.
P.S. I know there are many bladers who would think this is ******, but the classes should be balanced so everyone have chances to have fun.
