Diana's Ult changes

Recently Diana's ult was changed so that if her ult gets interupted after she tries to jump to a moonlit character, it wont go on cooldown. Doesn't this just make her more like Akali? Whats the point of interupting her ult if she will just use it again? How is this not anti-counterplay? Can someone explain the logic behind this? I feel like she's already so similar to Akali, now she is just more faceroll and it takes away some skill. Could it at least just cut the cooldown in half, or reduce it by some amount?
