The new ahri changes

Yes, Ahri is definitely strong right now. She has an insanely high win rate, and has a safe laning phase due to her q's mov speed boost. However, is nerfing the w really the way to balance Ahri? Lowering the range from 750 -> 600 seems overkill, and lowering the damage to boot seems to me a total nerf hammer. Meanwhile, the q mana cost changes hurt (but they're justified, considering how strong q is now). Congratulations, Riot. You officially made w one of the most useless spells in the game until Ahri gets a Lich Bane/ Rylais, both of which are not core items on her (they are late game options). Why not nerf the range on Irelia's point and click stun while you're at it? It does more guaranteed damage, has a 2 second stun, and allows very little counterplay. To sum it up, Ahri's w has gone through nerf after nerf. Please at least make the range 650 and increase the ap ratios a bit so the ability can actually be viable to use..
