Rework suggestion - Adding mobility to Kog'maw
I feel like Kog'maw is in a really weak spot compared to other adc's who have more utility and mobility in their kit. All he does now is press w and auto-attack, which is really one-dimensional. To fix this, and since he's a void champion, I think Kog'maw should have a new passive that allows him to burrow holes into the ground and escape like Rek'sai.
