Change to Talon's Kit

Some will say he's fine, others that he's OP. However I think he needs a slight buff/change to his E(Cut throat) ability, and here is why. Talon has no escape, before he had silence that allowed him to test his damage and run away alive. Now if he goes in he either kills or dies. I also think the .25 slow instead of silence was a bad trade for balance. 0.25 of a second is just simply not long enough of a slow in my personal belief, it should atleast be 1-2 seconds. That is not the change I am purposing however. The change I am purposing will not change any of Talon's E damage/slow. Here is my Idea for the change.
Current Cutthroat Cost: 35/40/45/50/55 Mana Range: 700 Talon instantly appears behind his target, briefly slowing them and amplifying his damage against that target. Talon teleports to the far side of his target, slowing them by 99% for 0.25 second and amplifying Talon's damage against the target by 3/6/9/12/15% for 3 seconds.
Changed Cutthroat Cost: 35/40/45/50/55 Mana Range: 700 Talon instantly appears behind his target, If target is an enemy or neutral monster, he briefly slowing them and amplifying his damage against that target. Talon teleports to the far side of his target, slowing them by 99% for 0.25 second and amplifying Talon's damage against the target by 3/6/9/12/15% for 3 seconds.
This change will give him a disengage/escape. Please note before voting No, That If Talon were to use E to all in on you, he would still have it on CD and not be able to get away from you before you get your chance. This is why I think this would be a fair and balanced change to his Kit. Please Vote and comment on why. Thank you for your time summoner's
