He is an awesome utility champ, and a great tank. I haven't tried the solo top because I like to tank with him, I find it a little trollish when someone wants to carry with Naut. Bot seems good, but he's so good at ganking I like him in the jungle. If you want to be the guy getting the kills, this isn't your build, if you want to be a good team player, and have mad kids saying thanks for clutching them kills, this is you. I always have a ton of assists, and I try to not last hit for the kill.
IF YOU HAVE TROUBLE DOING THE GANK AT LEVEL 3 WITH THIS BUILD GO CLOTH ARMOR 3 HP POTS. PUTS IT ON EASY MODE.
If you aren't invading then go Blue, wolves, wraiths, red, Gank. Gank top or bot depending on which team you are. Then either gank mid or get golems, wraiths then wolves then Gank again. If you aren't ganking you aren't doing your job. I usually skip golems altogether if I get a successful gank so I can then gank mid. Your awesome cc plus ghost allows you to gank even in a non vulnerable lane.
Get Q third because you can handle the jungle without it at the start, and it allows for a level three gank for that first blood, I always gank at level 3.
I usually try and get close and just use my Auto Attack. Then I use my E for the slow. The last thing I do is use the Q to ensure the final bit of damage and usually pull that first blood off.
Using that ulti
In team fights is really the only time this skill needs to be addressed. Don't use it on an up close and personal Master Yi if it's 5v5 just because your team told you to focus him. Your ulti can knock him up if you lock onto someone else in that direction but further away. Using it on the farthest squishy champ is usually the best way to go about firing it. Also, it's really cool for people like Shaco who can go invisible. You can follow the ulti line to know where they are, great for running into him in the jungle. Also, you can use your Q on the spot that the invisible guy just got hit up in the air from your ulti to pull them in, even if they're invisible your Q will hit.
Obviously change what your getting based on the enemy team. The only part of the build I always do the same is up through Heart of gold, the GP/10 is so helpful considering I focus around ganking rather than jungling. I sometimes even grab a GP/10 instead of those basic boots depending on the game. If they don't have a lot of cc or AP, I don't get merc treads. If they don't have a lot of AD I don't get Glacial so quick. Just buy smart. and WARD and get ORACLES. I didn't put that in the item build just because it's a game by game buy, but ward early, ward often.
Marks: I get the attack speed reds for that quick early jungling, I focus on getting through the jungle so I can gank asap. Getting first blood is more important to me than grabbing some magic penetration.
Seals and Glyphs: I get armor and magic resist because they are great for a tank
Quints: I've chosen movement speed, but this is where I think each player needs to decide for themselves. This is also a case where if you had a spare rune page you could change the quints based on the enemies. For example, grabbing the magic resist/health/armor quints. I do movement speed because once again, I enjoy the early ganks, and grabbing movement speed is always helpful. It allows me to not neeed to rush my boots. I can grab my gp/10 items and do just fine.
I should've clicked the defeat at the bottom because that was the last game I played with my AD Tank build. Since then just been winning. The one selected was a 70 minute game where we completely came back from us 0 towers, to them 8 towers.
Just showing you I test the builds out, so if you guys have an idea shoot it up in the comments and I'll try it out and let you know how it was. I can upload the stats of it with your user name too so you can see.
The Support Build
First thing, I'd either get CV or Heal based on your partner at bot, I like heal for the teammate. Also, I'd either get ghost, my preference, or teleport. Once again, preference. Naut is great at supporting though, auto attack stuns to save the teammate, getting wards to keep other jungler at bay, anddd you can do a little tower dive with your grab, then shield, plus uve that beautiful ulti. Plus it's always nice to have another big dude on the team, only thing is ur ad carry laner should make sure to have some sustainability considering you aren't a healer.
