I did get Gakido awhile back from 4 independent spins. A guildie got Ningendo from his 3rd free spin. Another spent 30 spins and didn't get anything useful. No one has gotten Konan on my server yet. Obviously statistically speaking the more you draw the greater chance you have, but neither 1x nor 10x spins give you more luck. Guess it really depends on how much you need Konan..

Good luck :P
