What if Karthus had a sticky wall instead of a slow field?
I've been mulling over the idea in my head and I think it'd be a good change for Karthus; the only issue I've ever really had with him is that his wall has felt horrible post-nerf, but it's kind of understandable because it's instant and it slows everyone for 5 seconds, not very good for counterplay
So what I propose it is to be made into a thicker, delayed wall that tethers all enemies close it, with their MR shredded and having their movement limited to a small area where they got snatched. I want to say it should ground, but exempt abilities that allow you to ignore CC so that he can still be countered by Vi, Malphite etc, but that's a little iffy
what u think
