interesting because darius should walk over talon like a bug. at least thats what i did when i played against him.
Whenever Darius went in for a last hit I would Rake him and turn around very quickly. Once I did it enough in would go in with a full combo which brings him down to 1/3 health. The Darius I fought wouldn't engage at that point and just leave to B or stick around with pots and die to the next combo.
@Wolf that's why I like Nocturne jungle so if I see stupid builds like that I can just build into a faux carry.
