I don't think Nami KSes too much. Maybe I just play her a little different, but I had a lot more trouble with release Lulu. Lulu had a bug where Pix damage would always count as Lulu's damage even you used him on your ally. So, I would end up stealing a bunch of creeps from my ADC, and late game I would even accidentally steal a kill or two. Even now, I still steal kills as Lulu trying to slow or get vision on the enemy we're trying to kill.
On the other hand, with Nami, if my team is all chasing down a low-health enemy and I know we're not going to catch him, I have absolutely no qualms about using surging tides on the person leading the chase and letting the splash take the kill. That's a kill secured, not stolen, in my book.

No Twin Shadows, Hermes? I find that item very valuable especially if the other team is trying to bait baron. I can check to see if they're sitting in a bush from the comfort of very, very far away. It's saved my team a lot of times.
