What YPN said. It doesn't have to be a persistent thing, like how it is with Karthus's Q. Like, for Kog'Maw's ult, just show the danger zone for like half a second, maybe the same for when his passive activates. Yes, there's a level of skill involved with knowing ranges and memorizing AoE widths, but sometimes it really is just spitballing and feels unfair.
