Viktor - W should ground
So Cassiopeia got this grounded ability on her W which is now totally useless on her because old miasma was much better against mobile characters. After you have driven my Cassio against a wall I played now Viktor since i like the how you changed his spells.
Viktor is now more of a dps hero who relies on people staying in his spells while being very immobile and fragile himself without any real CC. His W mostly works as zoning tool and it's very hard to hit the stun alone in the middle lane.The slow isn't something really worth mentioning. Especially against mobile characters who can jump out of your ultimate and E. After you took his silence from his ultimate he lacked a little bit of a tool against them.
So why not give him the grounded effect on his W? It would make perfect sense since the spell works with gravity. People should not be able to jump out easily and people trying to fly over/through it should stop shortly after they enter the area. It#s still possible to walk out of this spell since the slow isn't really much early levels.
I think this would synergize very well with Viktors new kit since the recent changes made him weaker against mobile burst heros (at least i think so).
