i think you should do further testing..or be rlly rlly noob. everytime i pk with baba warriors they fail leg cut 100%. im fighting some random scrub in +5 gear and hes spams leg cut on me lol........................................ things in ko are not easy to test because bugs are constantly changing and what not, and many things dont work already..i mean when they made lugias they put 25 dex on it for a reason...however because everything is bugged it might not do shit. but it could be different for dex coming from jewelry or armor.
point is it would take a ton of testing to get all aspects correct, get your avedon8 cause it rapes much harder regardless of leg cut success rate. and get your dual fov2 or atleast 1 so you can get some more resist, and hope that dex increases your legcut like its suppose to.
