Winds Of War - T: Leona & Garen, AD DPS:Ezreal & Garen, Support/AB dps: Sona/Leona/Janna

Simple tactics, Fast moment group with all using speed+ runes aswell as adding janna's speed buff in start to gain the first kill option if so is liked.

But basicly the group is all about movement in the battle aswell as having garen + Ezreal to hunt down runners with the aid of Janna. Else group battels will start with janna's tornado followed up with leona and garen charge with a support stun from Sona. Then Ezreal and garen aims the enemy cc's & support as Janna and sona support group and leona briging down the enemy heavy hitter/tank. Janna should try to keep her bubbel on the tank or the one closes to the chased target to optimize group potential. And sona should stay with the tank at all time. Sona can be changed for soraka if so please but do mind you will lose the sona benefits then.

All in all the build ain't needed to follow my choices but are just a quick setup I did, you can put your skills and take which items you seek to fit best. So don't worry to much following to the letter is more like a guide line to what i think could work for a fast moving group, Flash probly is better then ghost but added ghost as it increases speed even more hence the name "Winds Of War".
