And? The game is supposed to be about having fun. And nothing is fun about watching one character mow down an entire team without losing HP because she can spell vamp herself to full life by spamming an AoE ability with a .5 second cooldown.
They care enough to completely nerf Janna into the ground for some weird ass reason, they care enough to give Evelynn 10 charges of her Q, they care enough to make various damage/ability adjustments (all of which is accessible on the League Wiki if you'd like to read up on them).
So if they care enough to make any buffs/nerfs at all, then they care enough to keep the game feeling relatively fair. And NOTHING about Akali in URF feels fair.
