Here is how I build, I know, it's 0 damage, but it's also 0 cs and much fun and really feeds your carry epic kills.

Gold generation seals and quints, armor reds to make up for non-armor seals and mr/level (or flat, I just prefer per level for bot lane as you likely won't fight a mage til later on) with 0/9/21 masteries. I go CV and flash for good utility.

Start off with a Faery Charm, 3 Sight Wards or 1 Vision and 1 Sight (and you will stock up on these all game along with an Oracle's Elixir when you think you are tanky enough not to die for the rest of the game) along with 2 potions. I am not sure anymore if I get the wealth mastery to achieve this, if so it is only level 1. Rush Philo Stone and Heart of Gold as you would expect, then buy Mercury's Threads for epic escape capability. Get Force of Nature next, allowing for you to take a few hits, go behind you carry when you're low and let him finish off whatever ennemy is in front of him shooting in tornadoes and slows. Start with the health regen unless you get exactly 740 gold, if so get the cloak and go support mid for a short while. When you're back, get Warden's Mail (awesome lolz when focused) and finish Shurelya's Reverie for better initiation and whatnot. Then get Randuin's Omen, these two item's actives will make your opponents hate you. This is normally the time when the game is ending, if it is not go for a situational item (Frozen Heart, Banshee's if their mage is doing better than their ad, etc.) The method is to plant a tornado, run in with Shurelya (or keep it for a second), ultimate in the middle of their team, let your carry get a kill, Randuin's if he doesn't or is in danger, if you haven't used Shurelya use it to chase the remaining opponents.

With Janna people have the reflex to focus you, well mid-late game you are hard, hard to kill and pretty fast so... well they won't be able to focus you down fast enough while you on the other hand are disrupting their team so hard that your carries get an easy job. When you have a real tank with you on top of that, you are in business my friend.

You can go in their team trololo and come out, regen your health very fast with Randuin, Shurelya and Force of Nature it's just not funny, rush back in, keep disabling, make it so that when an ennemy is out of position they dearly regret it, it just allows for so much utility that your ennemies will have nightmares when Cait starts shooting.

0 Damage yet trololo wins. Done it so many times, it works, it rocks, worth your time. Go! Go!

Edit: made the items in bold so they are easier to spot

I prefer Locket over Randuin's because your team usually has a Randuin's by that time and Locket helps keep your carries alive longer without forcing you to butcher your positioning.

I could only see this build working if your team lacked tanks/initiators, but usually you won't have enough gold to get halfway done with that tank build meaning that you're still not tanky enough for the teamfighting that occurs in the midgame. If you've already finished five items, then you should use your gold for Oracle's and Elixirs while continuing to spam wards. If you still maxed those out and have 3k gold in the bank, then somehow the game has lasted way too long and everyone should have full builds and ~70 second death timers meaning that the next fight should determine the winner.

I do get Oracle's did you read?) and I get about 15-20 wards by then. No. Joking. I get the gold masteries, gp10 items and seals and quints to help me.
