What Jinx's positioning is so different. She can turret dive because passive, chase with basics, not ulti, zap must not hit minions, chompers to be used to zone, ulti used preferably as parallel to the pathing of the enemy as possible. Koggles just hides in the distance. Jinx goes hyper kiting. She is way too basic attack oriented to be comparable to Koggles. And her abilities behave so differently than his. And build is way different.If I recal correclty, Corki is Jinx her best/worst (how you want to describe it) counter. And Kog'Maw was actually the first champion I bought and played with. He isn't that hard if you can strategise and predict what will happen. If you can do so accurately most of the time then you don't need an escape. And his positioning is just like Jinx. There's not much difference between them in that aspect, that's why it was so easy to transfer. Or Jinx is just easy.
