Hey guys! Would really appreciate if you could check out my twitch channel, drop a follow as it helps me out a bunch! Twitch.tv/tokyodamonsta

Passive - TAILWIND: Janna gains bonus Move Speed moving towards allied champions and nearby allied champions gain this bonus when moving toward her. One of the reason janna is so great for roaming.

Q - HOWLING GALE: Janna is able to create a small storm that grows in size with time. She can activate the spell again to release the storm. On release this storm will fly towards the direction it was cast in, dealing damage and knocking away any enemies in its path. Janna Q is great for poking in lane, interrupting dashes/channels and escaping from danger.

W - ZEPHYR: Janna summons an air elemental that passively increases her Move Speed and enables her to pass through units. She may also activate this ability to deal damage and slow an enemy's Move Speed. The passive is lost while this ability is on cooldown. Janna W is a great reason she is known for roaming. The MS boost allows her to be everywhere on time. The active is good for slowing enemies and getting a easy Q off.

E - EYE OF THE STORM: Janna conjures a defensive gale that shields an ally champion or turret from incoming damage and increases their Attack Damage. Janna E is a shield that scales very well and grants huge AD boost late game.

R - MONSOON: Janna surrounds herself in a magical storm, throwing enemies back. After the storm has settled, soothing winds heal nearby allies while the ability is active. Janna R is great for insane healing and interrupting engage.

Pros and Cons of locking Janna!

Pros:
- Can solo carry
- Best peel in the game
- Insane scaling
- One of the best roaming supports

Cons:
- Not great blind pick
- Weak lane phase
- Cant engage

LANE PHASE:
Janna's weakest point is lane phase, her shield is very weak early, she is outdamaged by most supports and adcs. The most important part of laning with Janna is knowing when and how to use Q. Using Q randomly can result in losing all pressure in lane vs certain matchups for example: Tristana will find it very hard to just W into a janna with Q up, but if you have used Q she has a timer to do so. There are many examples like this: Lucian Pyke Ezreal etc... anyone who can engage will look to do so when you do not have Q up. On the other hand using Q from bushes during lane can create alot of pressure in lane and poke enemy laner out and sometimes lead to kills. Learning when and where to use Q comes with experience but a few things to think about when Qing in lane.
1.) Wave state - if you are going to Q through a minion wave it can push the wave. It can also mess up the minions for your ADC and make them lose farm.
2.) Movement Prediction - When using Q dont just aim where the enemy champ is standing, use your brain to Q where they will move. A good trick for this is to Q behind them and walk forward to W, Most reactions to this is to kite backwards. Obviously its situational, you cant just walk forward into 2 champs that can kill you.
3.) Can you use Q here? - a simple way to think about this is: Can they all in us? if answer is yes, keep Q for disengage. If no use Q for poke and get pressure.

If you are pushed in under tower all game you will find less chances to roam, your gameplan is to relieve pressure bot so that you can win the map. OF COURSE its matchup dependent and wincon dependent. If my adc is Draven i will look to play around bot more than usual, same for if my top is a tank.

Roaming:
Roaming is what makes Janna so great and fun.
I am looking to roam on every reset or AT least get vision before returning to bot.
Roaming is a hard concept to grasp but i would say most bad Janna's are afraid to leave their ADC alone. Janna isnt a great lane champ if you dont want to roam dont play Janna.
Janna isnt very mechanical, the skill to her is down to macro. Being where you should be at the right time. Giving your team numbers advantage when they need it.
You need to be careful when roaming that you dont completly sell your adc and let them get dove all game.
Times i look to roam:
- Wave is slow pushing towards my adc so he is safe and does not need to walk up to farm. (if my adc is diveable though i need to look to be back bot to cover it)
- My adc is resetting and im full hp with nothing to buy.
- I reset and see a play manifesting on the map.
- Herald spawn
- Grub spawn
Times i need to be bot.
- Wave is slowpushing towards enemy bot
- Enemy are looking to dive ally ADC
- We need XP still, lvl 11 is really strong for Janna.

There are times where i dont go by these rules, again its experience and your own judgement whether if you want to roam or not. Play around your wincon mostly.

Teamfighting:
Teamfighting isnt very hard for Janna. Use Q and R to peel, interrupt engage, heal your low allies. Again another Judgement on your end, using R to save someone can be not worth. For example saving ult for your 10 - 0 ADC with 1k bounty is way better than using it to save 0 - 5 teammate who is dying for fun.
Redemption heals alot, but takes time to drop, dont be scared to use it.

Runes and build are very linear. I build Moonstone everygame as it is 100% the best for Janna and has good synergy with your runes.
Glacial is just the best rune for now on Janna, if something changes i will update it.

Moonstone - Redemption is core and you are very OP with these items. But sometimes i will look to build Antiheal 2nd if its needed "vs soraka sona vlad etc"

As for items after, all situational:
Staff - with strong ap champs
Ardent - with strong auto attacker champs
Chemtech - vs alot of healing
Wardstone - very good late game for more vision control

- Janna E can be used on towers to save some HP or even stop enemy team from getting a plate.

- Janna gains heal and shield power when she slows or knocks up and enemy champ. So if you can do this before using E, R or even redemption you will get more worth out of them.

- Careful when using R as it can also save enemy champs.

- Using Q from a bush wont show that it is charging unless you leave the bush.

- Using E will stop your ult.
