Meh saw the title and wanted to do this. I like the guide but I have to disagree with some points. I believe that Clairvoyance and Clarity are useless. I always prefer exhaust as Janna because Janna is mainly a disengage champion, so she shouldn't be spamming her spells that often to need clarity. She also should be warding enough so that clairvoyance isn't needed. Exhaust fits perfectly with her, because it gives her extra peel

A lot of valid points are being made here, and I will revise the guide. I don't agree with some things, but nobody ever learned anything by trying to defend themselves against criticism.

...Just don't.

First off, why would you rush boots as Janna? I think your Zephyr is enough. And channeling your Monsoon to its full duration is pretty much suicide. It's not made for healing, although it can save an ally, but it's made for disruption.

You shouldn't leave your base without a Vision Ward. That's why you get Wealth . Rushing Aegis of the Legion isn't really important. If you are ahead, you can get a Shurelya's Battlesong or ask your jungler to get it.

Ghost, Heal or Clarity aren't viable. Clairvoyance is nice, but it would be rarely useful, unless you are against a support who is very strong at "ward wars", such as support Fiddlesticks, Blitzcrank or Leona. You forgot the only optimal spell that isn't Exhaust, and that's Ignite.

Oh and your setup looks like a powerspeedy Janna or something like that. Add a Shurelya's Battlesong active and you'll be faster than any Yi.

Did I say that Ruby Sightstone is not a mid-game item?

Choose the Mastery Wealth to improve you start option - at least three Sight Wards.

Janna has the highest win rate amongst supports currently. Support isn't underrated at all, it's mandatory 98% of the time. Turn on Comment to vote (C2V) to prevent any anonymous downvotes.

It really isn't, even amongst low tier players.

Okay, your guide is full of misconceptions on playing support.

1) Starting items are rubbish. Just about every other start is superior.

2) Masteries are definitely wrong and suboptimal.

3) Item choices are questionable. On Janna, Frozen Heart is better than Randuin's Omen. Enemies really shouldn't be focusing you unless you're out of position. You should be peeling and protecting your carries, not soak up damage.

4) You should be completing Ruby Sightstone before even starting Aegis of the Legion. Ruby Sightstone is not something you should be considering for mid-game. It should be bought by 15 minutes at most.

5) Clairvoyance actually isn't that great a spell, Heal isn't an option, Ghost isn't an option, Clarity isn't an option and you miss out the only other Summoner Spell that is a viable option, which is Ignite.

6) You miss out many possible items to buy on Janna. Morellonomicon, Abyssal Mask, zeke's herald.

7) Many of your 'tips' on playing Janna throughout the game are wrong. You should be out of the fountain by 10s, meaning going past inhib turrets by 25s is actually quite slow.

Your buff protection protocols are far too linear when there are many more ways to protect your buffs.

I'm not protecting my ADC. If he wanders somewhere where he gets himself killed, I'm not taking the fall for him. He should be helping your jungler pull his buff anyway. Only way he should die is if you get invaded and you lose the level 1 fight.

Your laning phases are bs, they pretty much don't exist.

I can think of many circumstances where I would want to send a Howling Gale down the lane.

Okay, I give up. Far too much stuff I disagree with to continue. Just take my downvote.
