The good thing about Cass rework...
Is it has potential with they new grounded CC. However, her new W isn't reliable enough to actually benefit from it. I mean, I want to actually ground a champ. But My experience after several test with Cass is I hardly ever land it. Plus the rest of the kit is paying for an overvalued new W.
Even the new Champ Taliyah E is better defense against dashing champs. I tested it and laughed to see Vaynes and Yasuos commit suicide in it.
So in the long run, when Taliyah is live, why would I pick Cass over her.
