Sated guinsoos tank nocturne?

While his DPS is good I think just going flat ad and tank is better. I don't play him if at all and the few times I have I think he is better with just flat ad and CDR so he can chase down his enemies. Stacking would take to long for his early game and I think ghostblade makes up for this very well imo. Guinsoo seems good but ive never tried it :D

I haven't tried that but in principle, building an item with AP and magic damage on a physical damage champion with almost no AP scaling seems bad. It's probably a good 2 item power spike but it doesn't scale at all with later penetration items or anything.
