Eh, leblanc had a high win rate long ago when she had dfg and silence. She was at a 43 win rate now shes rising to a 47 win rate. So shes doing better... But i for one thought she was just like Ahri minus the sustain and silence, simply because you blink the skill shot, right? Maybe that was only me... But i used to do stuff, Ahri was only capable of like getting Ahri's orb to run back to you for damage when you blink/position right. With LB S4, she was the same way until they nerfed it in a patch last season lolol. Say you W to gap close and smash R in your enemies face, place E purposely behind your enemy as if to miss it all together. W back for the chain to follow you, if that didn't seem to connect blink back to R and there it was. like a skillshot that returned back to you, albeit her E roots instead of dealing true damage. Never the less, it was some fun trick to do. Riot seen it as a bug, so they fixed it i think(Patch 4.4 for ethereal chains, "Fixed a bug where Ethereal Chains could still root an enemy even if LeBlanc was out of range when the secondary effect triggered." )...
doe! RIP lolol
