I find really interesting riot philosophy about " X champion is on radar"
They nerfed Malzahar, Brand and Swain, because they were "on radar" for a long time for being "too strong" ( despite no one complained about them). Interesting though, Wukong has 59% win ratio with people who has 125+ games with him, and has a 53,71% win ratio for A LONG TIME. Not only that, his play pattern is pretty stupid, since it is all point and click, and even when behind, he can easily burst out squishy with little time to react due to his stealth + E + youmuu ms. He only has problems against natural tanks top, because his kit is all about burst. But early on, he still can zone you a lot. Why wasn't he nerfed too?
Edit : People with 15-50 games have a 58.8% win ratio with him LOL, which means he actually doesn't require much skill to get full potential of him. Edit 2 : All the 3 mages who got nerfed not only are immobile, but skillshot retaliant ( Malzahar not exactly, because he can kill targets without his Q if ahead, but you need to be dumb to get that close to malzahar)
