Saving the sinking Titan

So, it's been some time since season 7 started and many things happened around the game. The meta had many significant changes which kept us players on the edge of our chairs, starring at the patch notes. And since a couple of patches, riot decided to nerf nautilus quiet hard. I personally think that it was kinda needed, but still there are many other tanks that are very similar to our titan of the depths. The tanks are still very strong and many of them feel overpowered at times(Galio, Sejuani, etc...). So why did riot nerf Nautilus so hard when he wasn't even that much better than the other choices for tanks. Because since the nerf, nautilus went from a top 3 top-laner to the lowest win-rate and even lowest overall placed top-laner. So i really hope that we don't let nautilus keep sinking to the bottom of the champion pool and get him back, atleast to a state where he's considered a champion. Pls show nautilus some love <3 Edit: After the W changes he has gotten worse RIP.
