Have a look here at @Nery 's build [1.1.4.1] Full Korba Trickster, no tricks and no greens, just pure melee!
I get it though, you wanna focus on RoS (which is somewhat the meaning of Korba set right?)
But, you do not even have RoS maxed!
plus you have no Raging Tempest for RR, no lethal assault and no exclusive (Stormcaller pact)
