Hi and welcome to my first ever build on League of Legends featuring Janna ,the storm's fury.

This build is made for the dominion,not for classic mode.

The main goal of this build is not to support or to kill, but just to cap points as fast as possible and to harass enemy team wanting to cap them.

There are those sorcerers who give themselves over to the primal powers of nature, forgoing the learned practice of magic. Such a sorceress is Janna, who first learned magic as an orphan growing up amidst the chaos that is the city-state of Zaun. Janna eked out what living she could on the streets. Life was tough and dangerous for the beautiful young girl, and she survived by her wits, and by stealing when wits weren't enough. The rampant magic that characterizes Zaun was the first and most alluring tool which Janna realized could both protect and elevate her. Janna discovered that she had an affinity for a particular type of magic - the elemental magic of air. She mastered her studies of air magic in a matter of months, almost as if she was born of it. Janna went from a street vagrant to an avatar of the air virtually overnight, stunning and surpassing those who taught her. Such a rapid ascension also changed her physical appearance, giving her an otherworldly look.
Seeking to right the injustice in the world (particularly the insanity that has become the city of Zaun), Janna has brought her talents to the League. She is a voice for the regulation of magical experimentation and a supporter of the development of techmaturgy, making her an indirect ally of the city-state of Piltover and the amazing techmaturgical minds that live there. Janna is also a new favorite of the League's many fans. She is often the center of attention at functions, fan appreciation days, and other celebratory events. There is something untouchable about Janna, however, and her affections can change as quickly as the wind.
"Do not be captivated by Janna's beauty. Like the wind, she is one gust away from terrible destruction."

I suggest for this build:

greater mark of replenishment9x Greater mark of replishment to get an advanced mana regeneration without item

9x Greater glyph of focus for less skill cooldown.Goal of these runes is to harass enemies as they are trying to cap the point.

greater seal of vitality9x greater seal of vitality to survive longer in teamfight

3x Greater quintessence of swiftness. As I said,the goal is to cap the point the fastest as possible,so these runes grant you a base speed bonus

Masteries are 8/0/22

Offense masteries:
Cooldown reduction is the second most important thing of this build,better CD is very useful to counter enemies capturing turrets.

No defense masteries

Utility masteries is for summoners spells( ), CD reduction & movespeed (3% increase Mspeed by 10)

Important Spells:
Flash:

Flash help you to get in and out of team fights,useful to get trought tree to get faster to a point.

Ghost:
The most important summoner spell of this build,it help you to move extremely fast to get on a point.

Useful spells:
Promote:
Getting a powerfuller minion to get down tower faster.

Ignite:
Ignite the an enemy during cap prevent him to cap

Useless spells:
Smite:
LOL !?

Cleanse:
Maybe be used if enemies slow you,but no enemies must be on your way.

First of all take a to get a faster movespeed (you can replace it by but when I run away I prefer run fast :D)

Follow as fast as you can with the to grant an active movespeed bonus and a better capture rate

Then you can follow with if your enemies don't stop running after you,or with .Any choise you make,take the second items right after.

After that,you are free of your items,but I recommend you to take a that grant you movespeed and aid in survive.

You can end the game with or with

Zephyr is the First skill to get maxed out, to get the passive effect.

Just get the shield to the level 1 and dont upgrade it since lvl 14.

The tornado is very usefull,upgrade it at the same time with zephyr and the ultimate.

As the game start just grab your boots of swiftness and get near of the top way.As the game start,just rush to top by activating your ghost.Run trought the forest to grab the speed boost.

The best way is to be followed by a fast champion (like Zilean or even Rammus).

If you are enought fast you must get to the top tower before enemy team,that let you the time to engage the tower,if you are luck you can even cap it.

In the mid game,you must have your Priscilla's & Shurelia's (or Rylai's).

Your game at the mid game is to jump between your tower to protect them,if an enemy is currently capping your tower ,just get behind the wall and spam them with the tornado,but take care of Sivir and Nocturne,their's shield can disable the spell and do not stop the cap.

If you are getting dominated,just defend and send them away with ultimate or tornado,and at the first gank just get backdoor and cap the farther point of the gank,let your team fight.

If you dominate,just continue on that way.

At the end of the game,if you are between 20 and 100 nexus HP while enemies have more than 300,you have just lost,unless enemies get a mass disconnect.

If you are between 50 and 100 while anemies have betwenn 100 and 300,you must defend at least 3 points and to not let them fall.

If you are at the same Hp ,defend and wait to the good moment to send a counter attack.

If enemies have <100 and your team more than between 100 and 200,continue to defend at least 3 point untuil the death

The main goal of this build is to cap and avoid to be capped.

The main inconvenient is that delete the assist side of janna,making it useless in teamfights
