Ahri in the meta is starting to work the tank meta has slightly shifted towards the attack speed side and ahri is become more versatile in ranked because of her mobility and high kill potential

Cons are that ahri is highly squishy in a team fight i would recommend baiting with spirit rush
rush in the rush out making them try jumping onto u, which thus means the enemy is grouped and your team can collapse and u can sit at the back chucking charms and orbs into the mix for obserd amount of damage although this tatic is highly risky it works very well for me
