Until Level 6 you should play defensive, because you got no flash. After Level 6 your Jump in "Cougar Stance" will give you high Mobility and a good escape Mechanism. Laning in "Cougar Stance" will restore your Mana for more Power in "Human Stance" and for faster stacking of "Tear of Goddess"

If you got your Furor Enchantment you should roam around the map and gank the other lanes. WIth your jump in Cougar Stance you won´t get catched.

With your full equip you will get very tanky. In team fights you should jump after the enemies squishiest target and burst it down. You could also stand in the back and poke the enemy team down.
