You nerfed Urgot to 48%winratte yet Hercaim and Riven sitting at 55% winrate without nerfs

Can someone please explain that bs for me ? Please? {{champion:6}} got nerfed once he reached over 51% and he wasn't even that top tier even, Yet {{champion:120}} and {{champion:92}} having 55% + winrate with being top tier for patchs and nothing happen to them. So what is the hell is that ? Right biased balance team.\ Infact {{champion:92}} {{champion:67}} {{champion:120}} {{champion:10}} outperform {{champion:6}} for 2 patchs yet you decide to nerf him only and not them while {{champion:10}} getting little pat with nerf on her mana cost only not her core passive.
