Has this been changed, or is it that you misread it all?

Because this slow is not OP at all, this ult is a single-target version of Nocturne, and this buff is shorter on a longer cooldown.

Move speed is maybe too strong, however. Only Zilean has this, but without attack speed.

And you messed up Q cooldown (though I think I rememeber something that it worked weird when putting it in).
