Discussion: Fleshing out the Kinkou Ninjas
Much like that other Pantheon thread, I think it's worth noting that there is a group that could use some fleshing out story-wise.
The Kinkou Order ninjas.

At least in
we get his feels and drive to be the best that sets him to the dark side. The three above said nothing about their personality, it's mostly about "We are stoic and we must fulfill our mission. Balancebalancebalancebalance." I get that Shen's backstory and training required him to do so, but it's like there's no development once Zed enters the picture, even if he's the one mostly affected. If he was supposed to be the type of 'Mysterious Protector', his quotes also didn't show much, it's mostly about BALANCE and HONOR.
Akali is at least a bit better, but not by much. Her lore just explains how she came to attain her title Fist of Shadow, and that's it. Nothing else. She only sticks out a little because she is dedicated on killing Zed, mostly out of the fact that he's a serious balance disruptor, but there were subtle hints that there's more about it (such as her title, or statements that Zed finds her disappointing for wasting her talents in Kinkou), but again, that didn't show in-game or in-lore.
Kennen is probably the worst offender in this. Yeah, I know he was supposed to be a ninja enforcing balance, but it's said that his personality is extremely jumpy and full of energy. And yet his quotes exudes stoicism for the most part. So is he a stoic yordle ninja or a hyperactive yordle ninja? Heck, if he would emulate Naruto, even if it's unoriginal, I think it'd make him stick out more.
Bottom line, I can see that amongst ninjas, Zed is going to be the fan favorite, because his story and personality is more fleshed out, whereas the Kinkou, not so much, seeing that they are like relics of the old type of League champions, much like Pantheon (added to fill in the niche, Stoic Badass Ninja for Shen (kudos for making him tanky), Non-human Jutsu Ninja for Kennen, Stealthy Assassination Kunoichi for Akali).
I know they're probably FAR from being updated, but let this be a food for thought for awhile.

Gragas have some ties to pirates?)
Graves and
Fizz are from Bilgewater. Reboot them to be a bit more pirate-y and BOOM! Can you imagine?! :P
