Viktor E change

I was thinking about potential changes to kit that would give him a slight bump in all around effectiveness.

After his last big changes(slower ult, longer e delay) and getting nerfed around the same time, he lost too much power. So, without changing any of the big changes, I thought of adding a slow to the first part of E.

E-Death Ray TARGET RANGE: 525 SPEED: 1350 COST: 70 / 80 / 90 / 100 / 110 mana COOLDOWN: 13 / 12 / 11 / 10 / 9

Active: Viktor uses his synthetic arm to fire an energy beam 500 units down the target path, **SLOWING AND **dealing magic damage to every enemy it hits. The arm can fire in any direction from any point within range, and does not interrupt Viktor's previous orders. SLOW EFFECT: .25 seconds at all ranks Magic Damage: 70 / 110 / 150 / 190 / 230 (+ 50% AP)  Augment: Aftershock: An explosion follows Death Ray's wake after 1 second, dealing additional magic damage.  Aftershock Magic Damage: » 20 / 60 / 100 / 140 / 180 (+ 70% AP)

I do not think this would make Viktor OP. Rather, it would reward Viktor for landing a difficult skillshot while making him much less dependent on .
